Efficient Certificateless Aggregate Signature Scheme for Performing Secure Routing in VANETs

Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020
Certificateless public key cryptosystem solves both the complex certificate management problem in the public key cryptosystem based on the PKI and the key escrow issue in the public key cryptosystem based on identity. The aggregator can compress n different signatures with respect to n messages from n signers into an aggregate signature, which can help

Cryptanalysis and Improvement of Three Certificateless Aggregate Signature Schemes

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
The certificateless aggregate signature (CLAS) scheme is a very important data aggregation technique that compresses a large number of signatures from different users into a short signature. CLAS can reduce the total length of a signature and the computational overhead of signature verification and is therefore highly suitable for resource‐constrained ...

Cryptanalysis of Compact Certificateless Aggregate Signature Schemes for HWMSNs and VANETs

IEEE Access
Certificateless cryptosystems resolve the critical problems in public-key cryptosystems and identity-based cryptosystems. A certificateless aggregate signature scheme aggregates multiple signatures of multiple signers into a single signature that ...
