摘要：

We propose a cryptographic scheme based on spatiotemporal chaos of coupled map lattices(CML),whichis based on one-time pad.The structure of the cryptosystem determines that the progress in decryption implies theprogress in exploring the dynamical behavior of spatiotemporal chaos in CML.A part of the initial condition of CML isused as a secret key,and the recovery of the secret key by exhaustive search is impossible due to the sensitivity to theinitial condition in spatiotemporal chaos system.Specially the software implementation of the scheme is easy.
