BentSign:keyed hash algorithm based on bent Boolean function and chaotic attractor

摘要

In this study,we propose a novel keyed hash algorithm based on a Boolean function and chaotic attractor.The hash algorithm called BentSign is based on two Signature attractors and XOR function and a bent Boolean function.The provided theoretical and experimental results confirm that the novel scheme can generate output hashes with a good level of security,collision resistance,and protection against most common attacks.
