Novel Efficient Certificateless Aggregate Signatures
We propose a new efficient certificateless aggregate signature scheme which has the advantages of both aggregate signatures and certificateless cryptography. The scheme is proven existentially unforgeable against adaptive chosen-message attacks under the standard computational Diffie-Hellman assumption. Our scheme is also efficient in both communication and computation. The proposal is practica...
متن کاملAn efficient certificateless aggregate signature with conditional privacy-preserving for vehicular sensor networks
Certificateless public key cryptography was introduced to solve the complicated certificate management problem in traditional public key cryptography and the key escrow problem in identity-based cryptography. The aggregate signature concept is useful in special areas where the signatures on many different messages generated by many different users need to be compressed. This feature is very att...
متن کاملComment on New Construction of Efficient Certificateless Aggregate Signatures
Aggregate signature can combine n signatures on n messages from n users into single signature, and the verifier should be convinced by the aggregate signature that n users indeed sign n messages. Since aggregate signature can greatly reduce the length of total signature and the cost of verification, it is widely used in environments with low bandwidth communication, low storage and low computab...
متن کاملNew Construction of Efficient Certificateless Aggregate Signatures
This paper proposes a novel construction of efficient certificateless aggregate signature (CLAS) scheme. On basis of the computational Diffie-Hellman (CDH) assumption, the proposed scheme can be proven existentially unforgeable against adaptive chosen-message attacks. The new scheme also requires small constant pairing computations for aggregate verification, which is independent of the number ...
متن کاملInsecurity of a Certificateless Aggregate Signature Scheme
Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. Very recently, Xiong et al. proposed a certificateless aggregate signature scheme provably secure in the random oracle model under the Computational Diffie-Hellman assumption. Unfortunately, by giving two kinds of concrete attacks, we indicate...
