Using time-stamp to improve the security of a chaotic maps-based key agreement protocol. (English) Zbl 1131.94017

Summary: Based on the semi-group property of Chebyshev chaotic map and time-stamp, we propose an enhanced chaotic maps-based key agreement protocol, which is more secure than the original one and can resist the replaying attack.
