Title:
Strongly Unforgeable ID-based Signatures Without Random Oracles

Authors: Chifumi Sato, Takeshi Okamoto, Eiji Okamoto

Abstract:

In this paper, we construct a strongly unforgeable ID-based signature scheme without random oracles. The signature size of our scheme is smaller than that of other schemes based on varieties of the Diffie-Hellman problem or the discrete logarithm problem. The security of the scheme relies on the difficulty to solve three problems related to the Diffie-Hellman problem and a one-way isomorphism.
