Certicateless Aggregate Short Signature Scheme [PDF]

, 2016
An aggregate signature scheme is the aggregation of multiple signatures into a single compact signature of short string that can convince to any arbitrary verifier participating in the scheme.

Comment on New Construction of Efficient Certificateless Aggregate Signatures

International Journal of Security and Its Applications, 2015
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 ...

Practical Certificateless Aggregate Signatures From Bilinear Maps

Journal of information science and engineering, 2010
Aggregate signature is a digital signature with a striking property that anyone can aggregate n individual signatures on n different messages which are signed by n distinct signers, into a single compact signature to reduce computational and storage costs.

Deep Attacks of a Certificateless Signature Scheme [PDF]

, 2013
Certificateless public key cryptography is an attractive paradigm since it eliminates the use of certificates in traditional public key cryptography and alleviates the inherent key escrow problem in identity-based cryptography.
