Certificateless Group Oriented Signature Secure Against Key Replacement Attack

چکیده
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificateless group oriented signature scheme based on bilinear pairing. In our scheme, only the members in the same group with the signer can independently verify the signature. We prove the signature scheme is existential unforgeability under adaptive chosen message attack in random oracle model.

A Provably Secure Ring Signature Scheme in Certificateless Cryptography
Ring signature is a kind of group-oriented signature. It allows amember of a group to sign messages on behalf of the group withoutrevealing his/her identity. Certificateless public key cryptography wasfirst introduced by Al-Riyami and Paterson in Asiacrypt 2003. Incertificateless cryptography, it does not require the use of certificatesto guarantee the authenticity of users’...
متن کاملAn efficient certificateless signcryption scheme in the standard model
Certificateless public key cryptography (CL-PKC) is a useful method in order to solve the problems of traditional public key infrastructure (i.e., large amount of computation, storage and communication costs for managing certificates) and ID-based public key cryptography (i.e., key escrow problem), simultaneously. A signcryption scheme is an important primitive in cryptographic protocols which ...
متن کاملA Secure and Efficient Certificateless Short Signature Scheme
Certificateless public key cryptography combines advantage of traditional public key cryptography and identity-based public key cryptography as it avoids usage of certificates and resolves the key escrow problem. In 2007, Huang et al. classified adversaries against certificateless signatures according to their attack power into normal, strong and super adversaries (ordered by their attack power...
متن کاملKey Replacement Attack on a Certificateless Signature Scheme
Yap, Heng and Goi propose an efficient certificateless signature scheme based on the intractability of the computational DiffieHellman problem, and prove that the scheme is secure in the random oracle model. This paper shows that their certificateless signature scheme is vulnerable to key replacement attacks, where an adversary who replaces the public key of a signer can forge valid signatures ...
متن کاملOn the security of a certificateless short signature scheme
Certificateless cryptography has attracted much attention due to its distinctive features. By eliminating the certification costs in traditional public key cryptography and addressing the private key escrow problem in identity-based cryptography, certificateless cryptography has become a mesmeric paradigm for developing various cryptographic primitives. Digital signatures with short signature l...
