Hash Algorithms and Security Applications
2003The security services required to guarantee a fully protected networking system are [76, 29]: Confidentiality - protecting the data from disclosure to unauthorised bodies Authentication - assuring that received data was indeed transmitted by the body identified as the source Integrity - maintaining data consistency and ensuring that ...

Secure Hash Algorithms and the Corresponding FPGA Optimization Techniques
ACM Computing Surveys, 2020Cryptographic hash functions are widely used primitives with a purpose to ensure the integrity of data. Hash functions are also utilized in conjunction with digital signatures to provide authentication and non-repudiation services. The SHA has been developed over time by the National Institute of Standards and Technology for security, optimal ...

A new secure and fast hashing algorithm (SFHA-256)
2008 National Radio Science Conference, 2008This paper presents a new secure and fast hashing algorithm based on the generic 3C construction. This construction is obtained by modifying the Merkle-Damgard (M-D) iterated construction used to construct iterated hash functions arid it is more resistant against the recent differential multi-blocks attacks and the extension attacks than the M-D ...

Investigating the Utilization of the Secure Hash Algorithm to Generate Electromagnetic Noise
Proceedings of the 9th International Conference on Signal Processing Systems, 2017This research introduces an electromagnetic (EM) noise generator known as the FRIES noise generator to mitigate and obfuscate Side Channel Analysis (SCA) attacks against a Raspberry Pi. The FRIES noise generator utilizes the implementation of the Secure Hash Algorithm (SHA) from OpenSSL to generate white noise within the EM spectrum.
