Generic Constructions of Identity-Based and Certificateless KEMs
We extend the concept of key encapsulation mechanisms to the primitives of ID-based and certificateless encryption. We show that the natural combination of ID-KEMs or CL-KEMs with ...

Distributed Private-Key Generators for Identity-Based Cryptography
An identity-based encryption (IBE) scheme can greatly reduce the complexity of sending encrypted messages. However, an IBE scheme necessarily requires a private-key generator (PKG)...

Efficient Identity-Based Signatures Secure in the Standard Model
The only known construction of identity-based signatures that can be proven secure in the standard model is based on the approach of attaching certificates to non-identity-based si...

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...
