SIMD Instruction Set Extensions for Keccak with Applications to SHA-3, Keyak and Ketje
Proceedings of the Hardware and Architectural Support for Security and Privacy 2016, 2016 Recent processor architectures such as Intel Westmere (and later) and ARMv8 include instruction-level support for the Advanced Encryption Standard (AES), for the Secure Hashing Standard (SHA-1, SHA2) and for carry-less multiplication. These crypto-instruction sets provide specialized hardware processing at the top of the memory hierarchy, and provide ...

Concealing Ketje: A Lightweight PUF-Based Privacy Preserving Authentication Protocol [PDF]
Lecture Notes in Computer Science, 2017 In this paper, we focus on the design of a novel authentication protocol that preserves the privacy of embedded devices. A Physically Unclonable Function (PUF) generates challenge-response pairs that form the source of authenticity between a server and multiple devices.

MILP-aided cube-attack-like cryptanalysis on Keccak Keyed modes [PDF]
Designs, Codes, and Cryptography, 2018 Cube-attack-like cryptanalysis was proposed by Dinur et al. at EUROCRYPT 2015, which recovers the key of Keccak keyed modes in a divide-and-conquer manner. In their attack, one selects cube variables manually, which leads to more key bits involved in the

New MILP Modeling: Improved Conditional Cube Attacks on Keccak-Based Constructions [PDF]
Lecture Notes in Computer Science, 2018 In this paper, we propose a new MILP modeling to find better or even optimal choices of conditional cubes, under the general framework of conditional cube attacks. These choices generally find new or improved attacks against the keyed constructions based
