Generalized secure hash algorithm: SHA-X

2011 IEEE EUROCON - International Conference on Computer as a Tool, 2011
This paper defines a generalized SHA algorithm based on the SHA family rules. The proposed algorithm accepts arbitrary length message as input to generate message digest with the required length. It contains the initial values, constant values, padding, parsing, as well as the generalized main body.

Secure Hash Algorithms and the Corresponding FPGA Optimization Techniques

ACM Computing Surveys, 2020
Cryptographic 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 Comparative Study of Secure Hash Algorithms

2016
Important responsibility of every organization is to provide an adequate security and confidentiality to its electronic data system. Data should be protected during transmission or while in storage it is necessary to maintain the integrity and confidentiality of the information represented by the original data.

A new secure and fast hashing algorithm (SFHA-256)

2008 National Radio Science Conference, 2008
This 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 ...

Robustness and security of a wavelet-based CBIR hashing algorithm

Proceedings of the 8th workshop on Multimedia and security, 2006
A wavelet-based robust database hashing scheme is analyzed with respect to its resilience against image modifications and hostile attacks. A method to construct a forgery is presented and possible countermeasures are discussed.
