An ID-based authenticated key exchange protocol based on bilinear Diffie-Hellman problem
In this paper, we present a new ID-based two-party authenticated key exchange (AKE) protocol, which makes use of a new technique called twin Diffie-Hellman problem proposed by Cas...

Efficient Chosen Ciphertext Secure Public Key Encryption under the Computational Diffie-Hellman Assumption
Recently Cash, Kiltz, and Shoup [20] showed a variant of the Cramer-Shoup (CS) public key encryption (PKE) scheme [21] whose chosen-ciphertext (CCA) security relies on the computa...

A New Cryptosystem Based On Hidden Order Groups
Let G1 be a cyclic multiplicative group of order n. It is known that the Diffie-Hellman problem is random self-reducible in G1 with respect to a fixed generator g if (n) is known....
