Abstract: tBased on the technical shortcomings of two kinds of authentication systems of PKI and IBE, this paper introduces the authentication system of CFL about development backgrounds, history, patents and its technology advantages, such as decentralization, destorilization, one person one key, roots high security. CFLs Ukey has not afraid to steal. The technology properties of CFL authentication system also included process to process high security authentication within a machine, high security the scene to authenticate, mandatory access control features and etc. This paper presents the products of CFL, and those under research. With the help of CFL, it can be provided further information in the network information system high security protection about confidentiality, integrity, availability, controllability and certification. Finally, the relationship between the CFL authentication system and the blockchain is discussed.
