Secure Regenerating Codes Using Linear Regenerating Codes and the All-or-Nothing Transform

This paper proposes secure regenerating codes that are composed of non-secure regenerating codes and a new all-or-nothing transform. Unlike the previous analysis of secure regenerating codes, the security of the proposed codes is analyzed in the sense of the indistinguishability. The advantage of the proposed codes is that the overhead caused by the security against eavesdropping is much less than that of previous secure regenerating codes. The security of the proposed codes against eavesdropping mainly depends on the new all-or-nothing transform.This is a product of research which was financially supported in part by the Kansai University Outlay Support for Establish Research Centers, 2015 “Further development of identification technology based on device fingerprints.

Artificial Metrics of Electric Devices and Their Applications

An Identification of artificial objects is lately receiving much attention for two reasons: the problem of counterfeiting of artificial objects, such as goods that use brand names, in international trade and the necessity of achieving a secure communication in the Internet of Things (IoT), which is a network of artificial objects that are embedded with network connectivity. To identify artificial objects, “fingerprints” of artificial objects, introduced during manufacturing and non-separable characteristics from artificial objects themselves, have to be discovered. This article reports fingerprints for acceleration sensors, flash memory, non-Foster matching circuits and elemental techniques for identifying fingerprints or measuring fingerprints with stability. This article demonstrates an encoding method for recording fingerprints securely in a distributed storage system
