Abstract: With the rapid development of information technology,the information security problem has been attaching more and more attention. The CFL,which can be achieved to the identity authentication, key exchange and encryption and decryption, is suitable for solving the information security problems from cloud computing, industrial control systems, big data and so on. Eight CFLs Schemes for classical information security problems are given, the superiorities of those are introduced.
