Post-Quantum Cryptography (PQC) is becoming popular since it offers protection against quantum attacks. CRYSTALS-Dilithium is being considered as a promising NIST PQC standard candidate. It utilizes the Radix-2 Number Theoretic Transform (NTT). Its reliance on lattice-based cryptography and number-theoretic principles positions CRYSTALS-Dilithium as a strong contender for providing robust security in the era of quantum computing. Besides, the Radix-4 NTT divides polynomials into more parts than the Radix-2 NTT, making calculations more efficient by reusing values. In this paper, we improve the computational efficiency of CRYSTALS-Dilithium by implementing the Radix-4 NTT algorithm in both C and Rust programming languages. We verified the effectiveness through experiments in terms of signature and verification speeds. Additionally, we analyzed the assembly code generated by both languages to understand the performance differences.

RSA-like cryptosystems, based on the original RSA algorithm, are gaining attention as potential alternatives to traditional techniques. They offer better security, efficiency, flexibility, and compatibility in cryptography. However, recent studies have uncovered vulnerabilities in these variants, particularly to Wiener-type attacks, despite initial expectations of security comparable to RSA. In this paper, we further investigate the security vulnerabilities of a variant of this technique, namely the Murru-Saettone (MS) cryptosystem. Our investigation employs lattice-based attacks to exploit weaknesses in systems with small private keys. It demonstrates that if the private exponent is smaller than N1/4, where N is the product of two distinct balanced primes, the small exponent of the cryptosystem can be recovered.

CP-ABE emerges as an advanced cryptographic method that offers secure and precise access control in Internet of Things and cloud storage applications. Nevertheless, the original CP-ABE algorithm relied on the PBC library with a security level limited to 80 bits and is now outdated, making it vulnerable to attacks. To address this issue, we have introduced ELiPS-based CP-ABE, which boosts the level of security to 128 bits using the ELiPS library. While this enhancement improved the overall performance, the decryption functions remained computationally intensive. To tackle this, we previously optimized the decryption function by minimizing final exponentiations and inversions. In this paper, we evaluate and analyze the impact of these optimizations on decryption efficiency. Moreover, we compare the ELiPS-based CP-ABE with these improvements to the initial version and the original PBC-based CP-ABE. As a result, the combination of both optimization techniques resulted in an average 43.06% overall reduction in decryption time compared to the initial version of the ELiPS-based CP-ABE scheme, while in total execution, it led to a 25.27% improvement. Furthermore, there was an average 53.81% overall reduction in total execution time compared to the original PBC-based CP-ABE method.

CKKS homomorphic encryption is frequently utilized in cloud-based applications due to its ability to handle both real and complex numbers, ensuring the protection of sensitive data. However, the security of CKKS encryption relies on an encoding process to convert input data into a polynomial. While this process involves the Inverse Fast Fourier Transform (IFFT), there are two notable issues with IFFT: first, most multiplications between complex numbers require four multiplications between real numbers, and second, there are delays in processing due to data hazards. In this paper, we propose an effective way to handle these issues by substituting them using parallelization based on the sum of complex conjugates. This approach aims to reduce the multiplication cost, thereby improving processing time compared to IFFT.

Pollard's rho method is a widely used probabilistic algorithm for solving the Elliptic Curve Discrete Logarithm Problem (ECDLP). To enhance its efficiency, the skew Frobenius mapping (SFM) has been incorporated into the method, reducing the average number of steps required to find a collision. However, the combination of Pollard's rho method with SFM introduces the occurrence of fruitless cycles, which are computational loops that do not contribute to solving the ECDLP and hinder the overall attacking efficiency. This paper presents a comprehensive analysis of fruitless cycles in Pollard's rho method with SFM, focusing on their impact when applied to Barreto-Naehrig (BN) curves. We propose a scheme to mitigate the occurrence of fruitless cycles by optimizing the seed point selection to be adaptive according to situation. To validate the effectiveness of our proposed method, we perform comprehensive experiments and compare the results with the conventional Pollard's rho method with SFM. The results indicate that the proposed approach significantly reduces the occurrence of fruitless cycles, leading to faster and more efficient ECDLP attacks on BN curves.

Vehicular Ad-Hoc Networks (VANETs) are essential for modern transportation systems, but their openness exposes them to cyber threats. Authentication in VANETs is challenged by dynamic topology and high mobility, requiring robust mechanisms. Previously, we proposed an authentication system for VANETs using blockchain and Kerberos. Kerberos authenticator messages are stored in a blockchain ledger accessible to the Trusted Authentication Server (TAS) and Roadside Units (RSUs), resulting in minimal signaling overhead and authentication delay. However, the performance of the blockchain itself was not evaluated. In this paper, we investigate the blockchain's performance in a simulated VANET environment with 100 vehicles, 4 RSUs, and 1 TAS. Using Ethereum blockchain and Omnet++ simulation, we assess the blockchain feasibility in VANET authentication scenarios.

The proliferation of the Internet of Things leads to the sharing of more data among diverse stakeholders, ranging from individual users to large enterprises. However, ensuring the security of this data exchange while simultaneously minimizing errors during transmission presents a complex challenge. Due to the involvement of numerous devices and users capable of data sharing, the dynamic and heterogeneous nature of the environment leads to constant changes. In this paper, we integrate the Kyber algorithm for post-quantum security with Bose-Chaudhuri-Hocquenghem (BCH) codes for error correction. We validate our approach by transmitting images from the widely- used CIFAR-10 dataset in encrypted mode over noisy communication channels. The system demonstrates effective image encryption and robust error correction capabilities.

Global food security is a pressing issue that affects the stability and well-being of communities worldwide. While existing Internet of Things (IoT) enabled plant monitoring systems have made significant strides in agricultural monitoring, they often face limitations such as high power consumption, restricted mobility, complex deployment requirements, and inadequate security measures for data access. This paper introduces an enhanced IoT application for agricultural monitoring systems that address these critical shortcomings. Our system strategically combines power efficiency, portability, and secure access capabilities, assisting farmers in monitoring and tracking crop environmental conditions. The proposed system includes a remote camera that captures images of surrounding plants and a sensor module that regularly monitors various environmental factors, including temperature, humidity, and soil moisture. We implement power management strategies to minimize energy consumption compared to existing solutions. Unlike conventional systems, our implementation utilizes the Amazon Web Services (AWS) cloud platform for reliable data storage and processing while incorporating comprehensive security measures, including Two-Factor Authentication (2FA) and JSON Web Tokens (JWT), features often overlooked in current agricultural IoT solutions. Users can access this secure monitoring system via a developed Android application, providing convenient mobile access to the gathered plant data. We validate our system’s advantages by implementing it with two potted garlic plants on Okayama University’s rooftop. Our evaluation demonstrates high sensor reliability, with strong correlations between sensor readings and reference data, achieving determination coefficients (R2) of 0.979 for temperature and 0.750 for humidity measurements. The implemented power management strategies extend battery life to 10 days on a single charge, significantly outperforming existing systems that typically require daily recharging. Furthermore, our dual-layer security implementation utilizing 2FA and JWT successfully protects sensitive agricultural data from unauthorized access.

Pairing-based cryptography serves as a fundamental building block for a wide range of advanced cryptographic protocols, including Ciphertext-Policy Attribute-Based Encryption (CP-ABE), blockchain, zero-knowledge Succinct Non-interactive ARgument of Knowledge (zk-SNARKs), and Homomorphic Encryption (HE). A well-designed pairing library would catalyze progress in these specific applications and encourage innovation across various cryptographic protocols that rely on pairing. However, the CP-ABE framework relies on the PBC library, which has not been updated for a long time, needs higher security levels, and is vulnerable to multiple attacks, making it less practical. In contrast, the ELiPS library offers efficient operations related to pairing-based cryptography, delivering high performance while upholding a substantial security standard. To address the issues above, enhance performance, and strengthen security in CP-ABE, we adopt and implement the ELiPS as an efficient library for pairing systems into the CP-ABE framework, namely ELiPS-based CP-ABE. First, we generate a generator g. Then, we employ Shirase's technique to convert asymmetric to symmetric pairing as the precondition of ELiPS. After that, we make several modifications to the CP-ABE framework and choose the appropriate ELiPS functions for integration. Finally, we validate our proposal through experiments involving data access authorization scenarios. The results confirm the effectiveness of our proposal, showcasing reduced computational costs for almost all functions except for the decryption cost.

In today's interconnected digital era, email stands as a primary platform for communication across various fields, such as business, academia, and personal interactions. Since it operates on shared mediums, email is inherently susceptible to interception and misuse of sensitive information. To cover this issue, Pretty Good Privacy (PGP) ensures the confidentiality of email contents. However, while PGP effectively encrypts the body of messages, a significant vulnerability emerges during key sharing. Blockchain technology comes with its immutability aspect. Once data is embedded into the blockchain, modifying it becomes exceedingly challenging. This makes it a potential safeguard against the vulnerabilities in PGP's key sharing mechanism. Additionally, smart contracts remove the requirement of a Man-in-the-Middle for sharing key, which enhances the sharing key's security and builds trust among users. In this paper, we integrate the strengths of blockchain into the PGP encryption process, specifically targeting the key sharing vulnerability. Also, we adopt Elliptic Curve Cryptography (ECC) to ensure the confidentiality of the PGP's key. First, generate the PGP's key. Then, encrypt it using ECC. After that, deploy a smart contract and continue with the encrypted PGP's key transactions in blockchain networks. Through this integration, we aim to enhance the security, ensuring both confidentiality and integrity of the PGP's key. We demonstrated that the proposed system is workable by experimental observation.

Vehicular Ad-Hoc Networks (VANETs) are a prominent technology in the drive towards establishing smart transportation systems in the Digital Transformation (DX) era. These networks provide users with critical road information for optimal route selection and accident avoidance. However, the openness of VANETs environment makes them susceptible to various cyber threats. Therefore, authenticating the entities that join the network is necessary and crucial for ensuring the security and integrity of VANET communications. Kerberos is one of the authentication protocols that ensure security, as the password and key are never directly sent among the entities. However, ensuring secure and efficient authentication, especially in VANET handovers, remains a challenge. This paper introduces an innovative authentication system for VANETs that leverages the combined power of blockchain and Kerberos. The system stores Kerberos authenticator messages in a distributed ledger within the blockchain, accessible to Trusted Authorities (TAS) and all RSUs. This approach streamlines vehicle handovers and safeguards authenticator messages against adversarial tampering. It exhibits minimal signalling overhead and authentication delay, ensuring swift and secure authentication processes. We verify the proposal's effectiveness by simulating the VANETs environment with 100 vehicles, 4 RSUs, and 1 TAS using Omnet++ with the Tsushima, Japan area map.

Nowadays, global warming has considered a key environmental issue associated with the pursuit of sustainable societies around the world. Therefore, it appears to be critical how to achieve the best usage of an air conditioner (AC) to reduce unnecessary energy consumption. In addition, it would be beneficial to elders who tend to suffer from heatstroke in hot summers. However, the AC can be overused or underused, while the indoor temperature is adjusted without considering the outdoor condition. If the weather is cool outside, the AC should be turned off and the windows in the room should be opened. On the contrary, if the outdoor temperature is high, the AC should be turned on. In this paper, we propose an air-conditioning guidance system (AC-Guide) to optimize the use of the AC. This system periodically, 1) samples the temperature and humidity of the room with the sensor, 2) obtains the outdoor weather data from an API, 3) calculates the discomfort index (DI) for the indoor and outdoor, 4) detects the on/off state of the AC using the image, and 5) sends a message of requesting turning on/off the AC when the DI is outside/inside the comfortable range. For evaluations, we implement the AC-Guide using Raspberry Pi, and verify the effectiveness through simulations and applications in two rooms at Okayama University.

Purpose: For several decades, calligraphy has been popular among people in Japan, China, and even in the world. Traditionally, a teacher teaches how to write letters on a paper with a brush, and a student will imitate them by referring to the model letters. However, if a teacher is not available, this method will not be applicable either. This study aims to propose a calligraphy learning assistant system (CLAS) using projection mapping, which allows a student to learn calligraphy by him/herself. Design/methodology/approach: By following the letter writing video of a teacher that is directly projected on the paper, a student is able to learn the stroke order and writing speed in addition to the letter shape. Moreover, the letter portion practice function is incorporated in CLAS to allow a learner to repeat practicing hard portions of each letter. Findings: For evaluations, the authors implemented CLAS using Raspberry Pi and open-source software and asked students to use it. The results confirmed that CLAS is effective in improving calligraphy skills of novice students. Originality/value: With CLAS, a student can practice calligraphy using a conventional brush, ink and paper at a desk while looking at the model letter writing of a teacher projected on the paper using projection mapping.

This paper explains about the walking patterns of quadruped robots. This robot was made to be an observer robot. Therefore, being slick in movement is the main feature that must be owned by this robot. As a four-legged robot, the movement (forward, backward, shift left, shift right, rotate) requires an algorithm to control the synchronization movements of each leg. This algorithm consists of several poses (including the body, as well as all legs) and if arranged in sequence it will form a certain pattern of movement. Each leg has 3 DOF. The pose of each leg is represented in the cartesian coordinates (x, y, z axis), while the movement of each joint is represented in angular. It has solved using the inverse kinematics formula which is useful for converting leg coordinates into angular for each leg joint. By defining the walking pattern, the robot can more easily controlled by the direction and speed of its movement.

Internet of Things (IoT) has become popular with the development of technology, which allows each physical device identified, managed and recorded by computer. In the context of Wireless Sensor Networks (WSNs), it is important for everyone to know the latest information of the status of human health, for example the condition of the surrounding environment. In the paper, we proposed an implementation of environmental health conditions monitoring through WSN with fuzzy logic that could be monitored in real time anywhere and anytime. In our proposed system, we used a sensor temperature, humidity, Carbon Monoxide (CO) and Carbon Dioxide (CO2), luminosity, noise for node sensors. For decision-making environmental health conditions with fuzzy logic, we have 5 categories, such as Very Good (VG), Good (G), Medium (M), Bad (B) and the last is Dangerous (D). The data were sent from the sensor node to the gateway using ZigBee IEEE 802.15.4 standard. The data received from the sensor node were stored into the database provided by the gateway and to be synchronized with external databases (database server) using TCP/IP. Users can access the data sensor via the website or mobile application such as Desktop, PCs, Laptop, and Smartphones.

Easy sharing files in public network that is intended only for certain people often resulting in the leaking of sharing folders or files and able to be read also by others who are not authorized. Secure data is one of the most challenging issues in data sharing systems. Here, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a reliable asymmetric encryption mechanism which deals with secure data and used for data encryption. It is not necessary encrypted to one particular user, but recipient is only able to decrypt if and only if the attribute set of his private key match with the specified policy in the ciphertext. In this paper, we propose a secure data exchange using CP-ABE with authentication feature. The data is attribute-based encrypted to satisfy confidentiality feature and authenticated to satisfy data authentication simultaneously.

Recently, disseminating latest sensory information regarding the status of environmental health in the surroundings of human life is one of very important circumstances which must be known by everyone. These circumstances should be accessible at anytime and anywhere by everyone through any type of end-user devices, both fixed and mobile devices, i.e., Desktop PCs, Laptop PCs, and Smartphones. Wireless Sensor Network (WSN) is one of the networks which deals with data sensors distribution from sensor nodes to the gateway node toward a Data Center Server. However, there is a big possibility for many adversaries to intercept and even manipulate data sensors crossing the network. Hence, a secure data sensor exchange in the system would be strongly desirable. In this research, we propose an environmental health conditions monitoring system through WSN and its implementation with considering secure data sensor exchange within the network and secure data sensor access. This work may contribute to support a part of smart cities and take in part the Internet of Thing (IoT) technology. In our proposed system, we collect some environmental health information such as temperature, humidity, luminosity, noise, carbon monoxide (CO) and carbon dioxide (CO2) from sensor nodes. We keep the confidentiality and integrity of transmitted data sensors propagating through IEEE802.15.4-based communication toward a gateway node. Further, the collected data sensors in the gateway are synchronized to the Data Center Server through a secure TCP/IP connection for permanently storing. At anytime and anywhere, only legitimated users who successfully pass-through an attribute-based authentication system are able to access the data sensors.

In Internet of Things (IoT) era, The limitation storage on Wireless Sensor Network (WSN) can be solved by synchronized data sensors from the gateway node to the data center server. Data in the data center can be remotely accessed by the user at any time and anywhere from end user devices such as PCs, laptop PCs, and smart phones., and data should be accessed securely. The Only legitimated user can access the data sensor from an environmental health data center. CP-ABE (Ciphertext-Policy Attribute-Based Encryption) is becoming a robust cryptographic scheme solution to this issue. To enable a secure data sensor sharing and access on an environmental health data center, we propose a secure system model using CP-ABE which ensures confidentiality, integrity, and user privacy features. Experimental results prove that the implementation of CP-ABE does not overload the system.
