Secure Hash Algorithm SHA-3

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...

Instruction sequence expressions for the secure hash algorithm SHA-256

The secure hash function SHA-256 is a function on bit strings. This means that its restriction to the bit strings of any given length can be computed by a finite instruction sequence that contains only instructions to set and get the content of Boolean registers, forward jump instructions, and a termination instruction. We describe such instruction sequences for the restrictions to bit strings ...

SHA-3: The BLAKE Hash Function

A global competition is currently taking place to select a hash function which will become a new standard in the field of cryptography. The competition was announced in 2007 by the National Institute of Standards and Technology (NIST) to find a successor to its previous Secure Hash Algorithm (SHA) standards, SHA-1 and SHA-2. The submissions have been narrowed down to a set of five, judged by th...

SHA - 3 and The Hash Function

Efficient FPGA Hardware Implementation of Secure Hash Function SHA-2

The Hash function has been studied by designers with the goal to improve its performances in terms of area, frequency and throughput. The Hash function is used in many embedded systems to provide security. It is become the default choice for security services in numerous applications. In this paper, we proposed a new design for the SHA-256 and SHA-512 functions. Moreover, the proposed design ha...
