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 OFDM communications based on hashing algorithms
SPIE Proceedings, 2007In this paper we propose an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system that introduces mutual authentication and encryption at the physical layer, without impairing spectral efficiency, exploiting some freedom degrees of the base-band signal, and using encrypted-hash algorithms.

Design of Hash Algorithm for Blockchain Security
2022Blockchain is the invention that permits digitally generated information to be allocated without being copied. Blockchain technology is the heart of the new internet (i.e., virtual currency). Emerging clever settlement structures over decentralized cryptocurrencies permit jointly suspicious events to transact competently without relying on third ...

Security and Robustness Enhancement of Existing Hash Algorithm
2009 International Conference on Signal Processing Systems, 2009In wireless communication for data integrity hash functions are commonly used. It is also an important cryptographic primitives, which is very critical for data integrity assurance and data origin authentication in security services. SHA hash functions are set of cryptographic hash function designed by NSA.

Hash Based Message Authentication Code Performance with Different Secure Hash Functions
International Computer Science ConferenceHash-based Message Authentication Code (HMAC) is a widely used cryptographic algorithm that combines a hash function with a secret key to ensure the integrity and authenticity of data. The performance of HMAC relies on the underlying hash function.

With the significance of data security increasing, hashing has become a vital part of both the computer sciences and mathematical research. Even though the first secure hashing algorithm has been defined by NIST decades ago, research on the field of secure hashing algorithms is now more relevant than ever. However, the choice of which security level to
