Abstract:

To Solve the problems in identity-based encryption (IBE) Scheme, such as the difficulties of the trusted authority TA(trusted authority) authenticating the users and transmitting the private key to them, the fingerprint identity-based encryption FIBE(fingerprint identity-based encryption) scheme based on IBE and fingerprint authentication is proposed. It applies the fingerprint hash matching algorithm to network authentication system and solves four problems in IBE. Moreover, the fingerprint feature is protected. The TA does not need to be online in the authentication process between the users, and is suitable for the condition of vertical authentication.

Key words: identity-based encryption, fingerprint identity-based encryption, fingerprint authentication, fingerprint certificate, fingerprint hash, fingerprint hash matching
