In many network communications it is crucial to be able to authenticate both the contents and the origin of a message. Digital signatures based on public key schemas are used for such authentication.

The vulnerability in the SHA-1 one-way hash function, which recently rocked the cryptographic world, is not seen as a threat to a new generation of one-time password products based on the encryption ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...
