Abstract: Based on high effective locations algorithm and error estimate, improvement of the public-key scheme based on Chebyshev maps proposed recently was presented and a key agreement protocol was given. Experiment results and analytic results show that it is very secure and practical.

Key words:  Chebyshev map, chaos, public key cipher, key agreement
