%X Based on strong chaoticity of the torus automorphisms, a public key encryption scheme is proposed by L. Kocarev. Theoretical analysis shows that discrete torus automorphism is related to Chebyshev polynomial, and the scheme is not a novel scheme but a special case of LUC system. Meanwhile, experiment test shows that the algorism proposed by Kocarev cannot make the scheme possess higher efficiency.
