Multi-Core Dataflow Design and Implementation of Secure Hash Algorithm-3
IEEE Access, 2018 Embedded multi-core systems are implemented as systems-on-chip that rely on packet storeand-forward networks-on-chip for communications. These systems do not use buses or global clock.

A New Image Encryption Algorithm Based on Chaos and Secure Hash SHA-256 [PDF]
Entropy, 2018 In order to overcome the difficulty of key management in “one time pad” encryption schemes and also resist the attack of chosen plaintext, a new image encryption algorithm based on chaos and SHA-256 is proposed in this paper. The architecture

Count based Secured Hash Algorithm [PDF]
IOSR Journal of Computer Engineering, 2012 This paper introduces a new approach to the Secured hash algorithm. The proposed algorithms takes the variable length input bit sequence and generate the fix length output as according to the algorithm. There are many constant values, used functions, pre-processing and hashing in SHA(1)(2)(3)(4). Here introducing new technique in which shifting of bits

A Secure Perceptual Hash Algorithm for Image Content Authentication [PDF]
, 2011 Perceptual hashing is a promising solution to image content authentication. However, conventional image hash algorithms only offer a limited authentication level for the protection of overall content. In this work, we propose an image hash algorithm with block level content protection.

An Improved Fast and Secure Hash Algorithm [PDF]
Journal of Information Processing Systems, 2012 Abstract —Recently, a fast and secure hash function SFHA – 256 has been proposed and claimed as more secure and as having a better performance than the SHA – 256. In this paper an improved version of SFHA – 256 is proposed and analyzed using two parameters, namely the avalanche effect and uniform deviation. The experimental results and further analysis

On Information Integrity Measurement with Secure Hash Algorithm (SHA) [PDF]
InSITE Conference, 2015 The “information age” as often referred to the modern society, has become heavily dependent on information systems. As this dependency increases, the threat to information security has also gained ground. Societies need to cater for the security of information, and this has led to the development of different information security techniques most ...
