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.

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

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.

Certificateless aggregate signature schemes: A review
2016 International Conference on Computing, Communication and Automation (ICCCA), 2016In the last decades security become a major issue due to increase technology. Among all the existing scheme certificateless aggregate schemes are very efficient techniques in recent scenario which is very helpful to provide security. Certificateless aggregate schemes are most attractive topic for researchers to give a lot of potential to secure our ...

A new certificateless aggregate signature scheme
Computer Communications, 2009Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. In this paper, we study aggregate signatures in certificateless public key settings. We first present the notion and security model of certificateless aggregate signature schemes.

Certificateless Ordered Sequential Aggregate Signature Scheme
2011 Third International Conference on Intelligent Networking and Collaborative Systems, 2011Ordered sequential aggregate signature scheme is a signature scheme in which each signer for a group signs an individual document, and guarantees both of the validity of the document and the signing order. Many ordered sequential aggregate signature schemes are ID-based scheme and inherit an intrinsic insider problem, called key escrow problem, of the ...

An efficient certificateless aggregate signature scheme
Wuhan University Journal of Natural Sciences, 2017Aggregate signature can aggregate n signatures on n messages from n signers into a single signature that convinces any verifier that n signers sign the n messages, respectively. In this paper, by combining certificateless public key cryptography and aggregate signatures, we propose an efficient certificateless aggregate signature scheme and prove its ...

Security Model for Certificateless Aggregate Signature Schemes
2008 International Conference on Computational Intelligence and Security, 2008Gong, Long, Hong and Chen defined the security model of certificateless aggregate signature schemes for the first time. However, there are some weaknesses exist in their model. In this paper, we point out some drawbacks of the security model of Gong et al.'s and present a new one.

Novel Efficient Certificateless Aggregate Signatures
2009We 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.
