Public-key coding system based on grey generation and Braid group

Based on the theories of grey data-generated algorithm and property of Braid group, an exchange protocol of secret key and cipher communication system depended on personal identification code generation are presented in this paper. Firstly, based on grey data generation and concept of braid group, the secret keys of both sides are obtained through the application of grey data generation to personal identification code; next, the exchange protocol of secret key which based on the generation of personal identification code is discussed according to the property of braid group. Lastly, the cipher communication system is presented based on personal identification code generating way.
