First Full-Fledged Side Channel Attack on HMAC-SHA-2
2021Side-channel attacks pose a threat to cryptographic algorithms. Hash functions, in particular those from the SHA-2 family, can also be an interesting target if some of their inputs are secret. HMAC is an important use case of a hash function, in which the input is partially secret and thus unknown to the attacker.

Novel Hardware Architecture for Implementing the Inner Loop of the SHA-2 Algorithms
2011 14th Euromicro Conference on Digital System Design, 2011Cryptographic algorithms are used to enable security services that are the core of modern communication systems. In particular, Hash functions algorithms are widely used to provide services of data integrity and authentication. These algorithms are based on performing a number of complex operations on the input data, thus it is important to count with ...

A flexible hardware implementation of SHA-1 and SHA-2 Hash Functions
2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011This paper summarizes the design of a reprogrammable Application Specific Integrated Circuit capable of performing all members of the Secure Hash Algorithm (SHA) group of Hash Functions. The need for high-speed cryptography is introduced, as well as the SHA-1 and SHA-2 Hash Functions and their operation.

On the hardware implementations of the SHA-2 (256, 384, 512) hash functions
Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003Couple to the communications wired and unwired networks growth, is the increasing demand for strong secure data transmission. New cryptographic standards are developed, and new encryption algorithms are designed, in order to satisfy the special needs for security. SHA-2 is the newest powerful standard in the hash functions families.

Deterministic Constructions of 21-Step Collisions for the SHA-2 Hash Family
2008Recently, at FSE '08, Nikolic and Biryukov introduced a new technique for analyzing SHA-2 round function. Building on their work, but using other differential paths, we construct two different deterministic attacks against 21-step SHA-2 hash family. Since the attacks are deterministic, they are actually combinatorial constructions of collisions.
