Cryptanalysis and Improvement of Three Certificateless Aggregate Signature Schemes [PDF]
Mathematical Problems in Engineering, 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 AccessCertificateless 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 ...
