A Framework of Variable-Length Source Encryption using Mutual Information Security Criterion: Universal Coding, Strong Converse Theorem

Yasutada Oohama, Bagus Santoso

In this paper we consider the variable-length lossless source coding for discrete memoryless sources. We proposes a new encryption framework for securely transmitting codewords ove…

A Framework of Distributed Source Encryption using Mutual Information Security Criterion and the Strong Converse Theorem

Yasutada Oohama, Bagus Santoso

We reinvestigate the general distributed secure source coding based on the common key cryptosystem proposed by Oohama and Santoso (ITW 2021). They proposed a framework of distribut…

Universal Coding for Shannon Ciphers under Side-Channel Attacks

Yasutada Oohama, Bagus Santoso

We study the universal coding under side-channel attacks posed and investigated by Oohama and Santoso (2022). They proposed a theoretical security model for Shannon cipher system u…

Algorithm Families for Computing Information-Theoretic Forms of Strong Converse Exponents in Channel Coding and Lossy Source Coding

Yutaka Jitsumatsu, Yasutada Oohama

The error exponent of a discrete memoryless channel is expressed in two forms. One is Gallager's expression with a positive slope parameter and the other is Csiszar and Korner's in…

Strong Converse Theorem for Source Encryption under Side-Channel Attacks

Yasutada Oohama, Bagus Santoso

We are interested in investigating the security of source encryption with a symmetric key under side-channel attacks. In this paper, we propose a general framework of source encryp…

Secret Key-based Authentication With Passive Eavesdropper for Scalar Gaussian Sources

Vamoua Yachongka, Hideki Yagi, Yasutada Oohama

We analyze the fundamental trade-off of secret key-based authentication systems in the presence of an eavesdropper for correlated Gaussian sources. A complete characterization of t…
