Implementation of Security Access Service using SHA-2 Algorithm

C Implementation of SHA-256 Algorithm

Hash functions play an important role in modern cryptography. Hash functions are widely used to provide services of data integrity and when they are used in combination with digital signature algorithms and MACs, they also provide authentication. In this paper a different scheme is proposed to improve the performance of the hardware implementation of the SHA-256 algorithm. The main focus of the...

Implementation of Secure Hash Algorithm Sha-1 by Labview

This paper presents the implementation of secure hash algorithm using VI LabVIEW environment toolkit. The SHA-1 used in many fields of security systems such as digital signature, tamper detection, password protection and so on. SHA-1 is a very important algorithm for integrity and authentication realization. The proposed algorithm of SHA-1 in this paper implemented by LabVIEW software from ente...

Replacing SHA-2 with SHA-3 Enhances Generic Security of HMAC

SHA-3: FPGA Implementation of ESSENCE and ECHO Hash Algorithm Candidates Using Bluespec

NIST has opened a public competition to develop a new cryptographic hash algorithm, and after the first round various algorithms have emerged as possible candidates. In this work, we have implemented on FPGA two of the candidates from the first round that are not known to be broken at this time, namely, ESSENCE by Jason Worth Martin and ECHO by the Cryptographic Research Group at Orange Labs, F...

Hardware implementation of a multi-mode hash architecture for MD5, SHA-1 and SHA-2

In this paper, we propose a unified architecture adapted to the field of embedded systems which combines commonly used hash algorithms in a single design in order to reduce area requirements and optimize the maximum frequency. We present an implementation of three hash functions: MD5 [8], SHA-1 [9] and SHA-2 [10]. Many similarities exist between these algorithms which help us to move towards a ...
