| Abstract(in English) | In this paper, a new identity-based key distribution system(ID-KDS)is proposed. In usual schemes, a trusted center must discard the user's ID information and use a different one when the center revokes a user's secret information. But in our scheme, there is no need for the center to do that. After revocation and renewal of a user's secret information, the center can use the same ID, which has been used before. Breaking our proposed scheme is equivalent to breaking the Diffie-Hellman cryptosystem, and impersonation depends on the difficulty of computing RSA. The conceptual structure of our proposed scheme is also discussed. |
