Revision of Tractable Rational Map Cryptosystem

Lih-Chung Wang and Fei-Hwang Chang

Abstract: We introduce a new public-key cryptosystem with tractable rational maps. As an application of abstract algebra and algebraic geometry to cryptography, TRMC (Tractable Rational Map Cryptosystem) has many superior properties including high complexity, easy implementation and very fast execution. We describe the principles and implementation of TRMC and analyze its properties. Also, we give a brief account of security analysis.
