Evolving Non-cryptographic Hash Functions Using Genetic Programming for High-speed Lookups in Network Security Applications [PDF]

, 2023
Non-cryptographic (NC) hash functions are the core part of many networking and security applications such as traffic flow monitoring and deep packet inspection. For these applications, speed is more important than strong cryptographic properties. In Terabit Ethernet networks, the speed of the hash functions can have a significant impact on the overall ...

Enhancing the Performance of Cryptographic Hash Function Using 2080 Bits Proposed Secure Hash Algorithm 160

International Journal of Scientific Research in Network Security and Communication
An on-way hash code or message authentication code is generated using the cryptographic hash functions. It used to be password storage, electronic data integrity, and check verification. Cryptographic hashing algorithms, which employ beginning value and key constant to boost algorithm complexity, have been proposed by a number of academics.
