The National Institute of Standards and Technology (NIST) has selected a new cryptographic hash algorithm through a public competition. The new hash algorithm is referred to as the Secure Hash Algorithm 3 (SHA-3) and is intended to complement the SHA-2 hash algorithms currently specified in Federal Information Processing Standard (FIPS) 180-3, Secure ...

Differential Fault Analysis of SHA-3
2015In this paper we present the first differential fault analysis DFA of SHA-3. This attack can recover the internal state of two versions of SHA-3 namely, SHA3-512 and SHA3-384 and can be used to forge MAC's which are using these versions of SHA-3. Assuming that the attacker can inject a random single bit fault on the intermediate state of the hash ...

Serialized lightweight SHA-3 FPGA implementations
Microprocessors and Microsystems, 2019Abstract In this article, we extend our study of lightweight FPGA implementations of SHA-3 published at ReConFig 2016. We use the shallow pipeline optimization technique for the slice-oriented SHA-3 architecture developed previously and examine additional aspects.

A hardware wrapper for the SHA-3 hash algorithms
IET Irish Signals and Systems Conference (ISSC 2010), 2010The second round of the NIST public competition is underway to find a new hash algorithm(s) for inclusion in the NIST Secure Hash Standard (SHA-3). Computational efficiency of the algorithms in hardware is to be addressed during the second round of the contest. For software implementations NIST specifies an application programming interface (API) along

On the hardware implementation efficiency of SHA-3 candidates
2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010The most well known and officially used hash function is the Secure Hash Algorithm-1 (SHA-1) and Secure Hash Algorithm-2 (SHA-2). In recent years serious attacks have been published against SHA-1. This led the National Institute of Standard and Technology (NIST) to organize an effort to develop a modern and more secure hash algorithms through a hash ...

Integral Distinguishers of Some SHA-3 Candidates
2010In this paper, we study structural Integral properties on reduced versions of the compression functions of some SHA-3 candidates: Hamsi-256, LANE-256 and Grostl-512. More precisely, we improve on the Integral distinguishers of Hamsi-256 (less time complexity or deterministic instead of probabilistic) and present the first known Integral distinguishers ...

Lightweight Implementations of SHA-3 Candidates on FPGAs
2011The NIST competition for developing the new cryptographic hash algorithm SHA-3 has entered its third round. One evaluation criterion is the ability of the candidate algorithm to be implemented on resource-constrained platforms. This includes FPGAs for embedded and hand-held devices.

Extracts from the SHA-3 Competition
2013The story of the SHA-3 competition starts with the presentation of surprisingly efficient attacks on several modern hash functions at Eurocrypt 2005 [1, 2] and at Crypto 2005 [3, 4]. Collisions were given for the hash functions MD4, MD5, RIPEMD and SHA-0.

Pipelined SHA-3 Implementations on FPGA
Proceedings of the Second Workshop on Cryptography and Security in Computing Systems, 2015Efficient and high-throughput designs of hash functions will be in great demand in the next few years, given that every IPv6 data packet is expected to be handled with some kind of security features.In this paper, pipelined implementations of the new SHA-3 hash standard on FPGAs are presented and compared aiming to map the design space and the choice ...

If X is sender of a message and Y is the receiver of the same, then X encrypts the same with Y’s public key and then sends the encrypted data to Y. It confirms about authenticity and authorization of receiver. If X sends message and Y receives, X encrypts the message with X’s private key and sends the encrypted data to Y.
