The effect by recycling of the resources in a process transformation mechanism

NOMURA Kazutaka, TABATA Toshihiro, TANIGUCHI Hideo

A process transformation technique has been implemented in Tender. The purpose of this technique is load distribution in distributed environment. This technique consists of three functions, which are the change of a program, the change of start point of a program and the change of a virtual address space in process execution. In order to utilize this technique efficiently, it is necessary to reduce the cost of the transformation. In this paper, we discuss how a resource recycle mechanism is applied to the process transformation. We also evaluate the process transformation and report the result of the evaluation.

Agent-based IDS for Dynamic Variation of Network Composition

KOTEGAWA Yuki, TABATA Toshihiro, SAKURAI Kouichi

IPSJ SIG Notes 117 ( 22(DPS-117 CSEC-24) ) 109 - 114 2004.3

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

Compared with IDS installed on a network, IDS installed on a host can use more information for intrusion detection. However, IDS installed on a host can detect intrusion into only the host. Therefore, when a host is newly connected to the network, it is necessary to newly install IDS into the connected host. In this paper, Agent-based IDS is proposed. The system can automatically install IDS into the connected host On the proposed system, the mobility of mobile agents can save the time and effort of introduction of IDS. Moreover, by simultaneous distribution of upgraded agents, efficient maintenance management is realized.

Program Birthmark Scheme with Tolerance to Equivalent Conversion of Java Classfiles

FUKUSHIMA Kazuhide, TABATA Toshihiro, SAKURAI Kouichi

IPSJ SIG Notes 23 ( 126(CSEC-23) ) 81 - 86 2003.12

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

This paper examines program birthmark scheme for Java in order to detect illegal thefts of Java classfile. Tamada et al. proposed birthmark scheme based on initial value assignments, the sequence of method call, and the inheritance structure. We show that the birthmarks based on initial value assignments and the inheritance structure can be modified easily. In addition, we propose a birthmark scheme using automata.

Implementation and Evaluation of Instant Synchronization InterProcess Communication on Tender

FUKUTOMI Kazuhiro, TABATA Toshihiro, TANIGUCHI Hideo

IPSJ SIG Notes 93 ( 42(OS-93) ) 25 - 32 2003.5

Language：Japanese Publisher：Information Processing Society of Japan (IPSJ)

InterProcess Communication (IPC) is used in many application programs. IPC is important and used in various ways. Especially exchanging data, a common form of IPC is message passing. However, in the message passing, since communication is completed in the combination of the send and receive operation, IPC cannot contain two elements simultaneously - the instant communication operation and the synchronization of data transfer. In this paper, we propose the mechanism of Instant Synchronization InterProcess Communication. We describe the implementation of this mechanism on Tender operating system. Also, we show the basic performance of this mechanism and evaluate this mechanism using an application program.

Design of Resource Enduring Mechanism Using Plate on Tender

To provide various functions such as process management and memory management, an operating system (OS) builds various kinds of management information on volatile memory. Data on volatile memory, however, is no longer available when a computer is turned off. This unreliability of volatile memory causes serious problem - if computer crashes, a computer cannot continue previous processing. One way to solve this problem is to make OS management information persistent. On Tender operating system, which we are developing, we define a resource as an object controlled and managed by the OS. Therefore, as long as we can make resources persistent on Tender, we can make OS management information persistent. In this paper, we propose resource enduring mechanism using plate, which makes data on virtual memory persistent, and explain the design of this mechanism.
