In the IoT era when a device is connected via the Internet, we can enjoy a great deal of convenience with the use of such devices, but a large number of users are not concerned about the attack from a third party. It is also meaningful for the user to have such a consciousness, but the person providing devices needs more specialized knowledge and awareness of the security. For such demands, a special education program called enPiT is held to provide an opportunity for undergraduate students to learn about cutting-edge information technologies and aims to cultivate human resources who have acquired the ability to solve specific problems in society. In this paper, we introduce the contents of \enPiT-Security advanced PBL exercise G" held in Okayama University and describe the helpfulness of the exercise and room for improvement based on the students' comments.

Wireless Body Area Networks (WBANs) play an important role in healthcare system by enabling medical experts to guide patients remotely. The unauthorized access of medical data from WBAN controller as well as the unreliable data communication may leads to risk for patients life. Currently, Chunqiang Hu et al., [1] proposed a data communication protocol by using Ciphertext-Policy Attribute-Based Encryption (CP-ABE) for a single file. The major limitation of Chunqiang Hu et al., [1] is that as the number of files increases, CP-ABE will suffer from parameters such as message size, energy consumption and computation cost. This paper proposes a more secure and efficient data communication scheme for WBANs by using an efficient File Hierarchy CP-ABE (FH-CP-ABE). The proposed scheme uses integrated access structure which is a combination of two or more access structures with hierarchical files encrypted. We evaluate the performance analysis of the proposed data communication protocol in terms of message size, energy consumption, computation cost and compared with Chunqiang Hu et al., [1].

—In cloud environment, profile matching is a key technique in applications such as health care and social networks. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is a suitable technique for data sharing in such environments. In this paper, we propose an asymmetric pairing based Hierarchical Multi-Authority CP-ABE (HM-CP-ABE) construction for profile matching. We utilize the fast Ate pairing to make the proposed HM-CP-ABE scheme efficient. The performance analysis of the proposed scheme shows improved efficiency in terms of computational costs for initialization, key generation and encryption using ELiPS library when compared with existing works.
