Abstract


Digital signatures, which can provide authentication, integrity and non-repudiation, play an important part in telecommunication and e-commerce during network transmission.In the traditional public key cryptosystem, the binding between a user’s identity and public key is implemented through a digital certificate issued by the certifying authority(PKI).However, the management of digital certificates requires high computation and storage, which makes the whole process very complex and aggravates the system’s burden.In order to simplify the process of certificate management, the concept of identity-based cryptosystem was introduced firstly by Shamir in 1984.In such a cryptosystem, the public key is the user’s identity or the information derived from the user’s identity, and the private key is generated by a trusted third party called private key generator(Pi^G).A great deal of identity-based encryptions and signatures were proposed by many people. We propose three new identity-based designated m signature based on bilinear pairings.The main contributions are as follows:In this paper, based on bilinear pairings, we propose two new identity- based designated signatures.The proposed schemes introduces two independent PKG to solve the secure trouble that the single PKG can impersonate the signers to forge their signatures.We proved that the proposed schemes are secure. In this paper, based on bilinear pairings, we propose a new identity- based short signature.The proposed scheme introduce two independent PKG.We proved that the proposed scheme is secure and efficient.
