Identity-Based Decryption
Identity-based decryption is an alternative to identity-based encryption, in which Alice encrypts a symmetric key for Bob under a trusted authority’s public key. Alice sends Bob...

A Biometric Identity Based Signature Scheme
We describe an identity based signature scheme that uses biometric information to construct the public key. Such a scheme would be beneficial in many repudiation situations for e...

Group Signature Where Group Manager, Members and Open Authority Are Identity-Based
We present the first group signature scheme with provable security and signature size O(λ) bits where the group manager, the group members, and the Open Authority (OA) are all id...
