On the Security of a Certificateless Aggregate Signature Scheme
IEEE Communications Letters, 2011Certificateless cryptography eliminates the need of certificates in public key cryptosystems and solves the inherent key escrow problem in identity-based cryptosystems. An aggregate signature scheme is a signature scheme which allows to aggregate n signatures on n distinct messages from n distinct users into a single signature.

An efficient certificateless aggregate signature with constant pairing computations
Information Sciences, 2013 An aggregate signature scheme enables an algorithm to aggregate n signatures of n distinct messages from n users into a single short signature. This primitive is useful in resource-constrained environment since they allow bandwidth and computational ...

A Secure and Efficient Certificateless Aggregate Signature Scheme
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2014 In this letter, we propose a new secure and efficient certificateless aggregate signature scheme which has the advantages of both certificateless public key cryptosystem and aggregate signature.

Compact sequential aggregate signatures
Proceedings of the 2007 ACM symposium on Applied computing, 2007In this paper, a new notion which we call compact sequential aggregate signatures is introduced and formalized. Informally, a compact sequential aggregate signature states the following thing: for a given message vector m=(m1, · · · mι), a public key vector PK=(PK1, · · · , PKι) and a path p=(v1, · · · , vι), where vi=(idi, PKi), the size of the third ...

Certificateless Aggregate Signature Scheme
2010 International Conference on E-Business and E-Government, 2010This paper puts forward a secure construction of certificateless aggregate signature scheme using bilinear maps. The security of our scheme is based on the infeasibility of the Computational Diffie-Hellman problem and is formally proven in the strongest security model of certificateless aggregate signature schemes.

A structured aggregate signature scheme
2010 International Symposium On Information Theory & Its Applications, 2010In multisignature scheme, verifiying the signing order is sometimes very important. A multisignature scheme in which generated signatures reflect the structure of signers, e.g. signing order, is called structured multisignature scheme and many such schemes have been proposed so far.

An Improved Certificateless Aggregate Signature
2014 IEEE International Conference on Computer and Information Technology, 2014Recently, Hou et al. Proposed an improved certificate less aggregate signature (CLASS) scheme based on Xiong et al's scheme. They also demonstrated the scheme is provably secure in the random oracle model. Unfortunately, by giving concrete attacks, we point out that Hou et al.'s scheme is not secure in their security model. Then, we propose an improved

Fault-Tolerant Aggregate Signatures
2016Aggregate signature schemes allow for the creation of a short aggregate of multiple signatures. This feature leads to significant reductions of bandwidth and storage space in sensor networks, secure routing protocols, certificate chains, software authentication, and secure logging mechanisms. Unfortunately, in all prior schemes, adding a single invalid

Cryptanalysis and Improvement for Certificateless Aggregate Signature
Fundamenta Informaticae, 2018In order to satisfy application in resource constrained environment, aggregate signature schemes have been widely investigated. Recently, He et al. pointed out that certificateless aggregate signature (CLAS) scheme proposed by Xiong et al. was insecure against the Type II adversary and presented an possible improvement.
