In-memory realization of SHA-2 using ReVAMP architecture
2021 34th International Conference on VLSI Design and 2021 20th International Conference on Embedded Systems (VLSID), 2021Emerging non-volatile memory (NVM) technologies with computation capabilities have heralded a new era of non- Von Neumann computing models. Redox-based Resistive RAM (ReRAM) is a prominent NVM technology, which offers high density, low leakage power and ability to perform functionally complete set of Boolean operations.

Randomness Analyses of the Secure Hash Algorithms, SHA-1, SHA-2 and Modified SHA
International Conference on Frontiers of Information Technology, 2019This paper introduces a security analysis scheme for the most famous secure hash algorithms SHA-1 and SHA-2. Both algorithms follow Merkle Damgård structure to compute the corresponding hash function.

Estimating the Cost of Generic Quantum Pre-image Attacks on SHA-2 and SHA-3
ACM Symposium on Applied Computing, 2016We investigate the cost of Grover’s quantum search algorithm when used in the context of pre-image attacks on the SHA-2 and SHA-3 families of hash functions.

Optimisation of the SHA-2 Family of Hash Functions on FPGAs
IEEE Computer Society Annual Symposium on Emerging VLSI Technologies and Architectures (ISVLSI'06), 2006Hash functions play an important role in modern cryptography. This paper investigates optimisation techniques that have recently been proposed in the literature. A new VLSI architecture for the SHA-256 and SHA-512 hash functions is presented, which combines two popular hardware optimisation techniques, namely pipelining and unrolling.

New Local Collisions for the SHA-2 Hash Family
2007The starting point for collision attacks on practical hash functions is a local collision. In this paper, we make a systematic study of local collisions for the SHA-2 family. The possible linear approximations of the constituent Boolean functions are considered and certain impossible conditions for such approximations are identified.
