Side-channel analysis of MAC-Keccak hardware implementations [PDF]
As Keccak has been selected as the new SHA-3 standard, Message Authentication Code (MAC) (MAC-Keccak) using a secret key will be widely used for integrity checking and authenticity assurance. Recent works have shown the feasibility of side-channel attacks against software implementations of MAC-Keccak to retrieve the key, with the security assessment ...

Abstract This article presents the design and implementation of a reliable computing virtual container‐based model with integrity verification for data processing strategies named the reliability and integrity verification (RIV) scheme. It has been integrated into a system construction model as well as existing workflow engines (e.g., Kulla and ...

Optimized Software Implementation of Keccak, Kyber, and Dilithium on RV{32,64}IM{B}{V}
With the standardization of NIST post-quantum cryptographic (PQC) schemes, optimizing these PQC schemes across various platforms presents significant research value. While most existing software implementation efforts have concentrated on ARM platforms,

Toward designing a lightweight RFID authentication protocol for constrained environments
Our article investigates the vulnerabilities of lightweight RFID authentication schemes, namely LRSAS+ and LRARP+, and proposes an enhanced version leveraging the χper$\chi per$ function to address their weaknesses. Through formal analysis and comparison with contemporary systems, we demonstrate that the improved scheme achieves robust security while ...

New techniques for trail bounds and application to differential trails in Keccak
We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as ordered lists of basic components in order to arrange

A survey on post‐quantum based approaches for edge computing security
The distribution of reviewed papers by focused area. Abstract With the development of technology and its integration with scientific realities, computer systems continue to evolve as infrastructure. One of the most important obstacles in front of quantum computers with high‐speed processing is that its existing systems cause security vulnerabilities ...

Higher-Order Side-Channel Protected Implementations of KECCAK
The efficient protection of security critical devices against side-channel analysis attacks is a fundamental need in the age of Internet of Things and ubiquitous computing. In this work, we introduce a configurable hardware design of KECCAK (SHA-3) which can be tailored to fulfill the needs of a wide range of different applications.

Superposition Attacks on Pseudorandom Schemes Based on Two or Less Permutations
We study quantum superposition attacks against permutation‐based pseudorandom cryptographic schemes. We first extend Kuwakado and Morii’s attack against the Even–Mansour cipher and exhibit key recovery attacks against a large class of pseudorandom schemes based on a single call to an n‐bit permutation, with polynomial O(n) (or O(n2), if the concrete ...
