This paper proposes a new ID-based proxy signature scheme based on the bilinear pairings. The number of paring operation involved in the verification procedure of our scheme is onl...
Group signature schemes are cryptographic systems that provide revocable anonymity for signers. We propose a group signature scheme with constant-size public key and signature leng...
Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a...
Abstract. In identity-based (ID-based) cryptosystems, a local registration authority (LRA) is responsible for authentication of users while the key generation center (KGC) is respo...

ID-based public key systems allow the user to use his/her identity as the public key, which can simplify key management procedure compared with CA-based public key systems. However...
