Abstract :
A collusion attack free identity-based non-interactive key sharing scheme (ID-NIKS) has been proposed. The security depends on the discrete logarithm problem furnished with a trapdoor of permutation. The center algorithm of ID-NIKS can also be applied for an ElGamal-like direct realization of identity-based cryptosystem (ID-cryptosystem).
