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.

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.

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.

Signtiming scheme based on aggregate signature
2008 IEEE International Conference on Intelligence and Security Informatics, 2008Timestamping is a cryptographic technique providing us with a proof-of-existence of a digital document at a given time. Combining both digital signature and provable time-stamping guarantees authentication, integrity and non-repudiation of electronic documents. In this paper, we introduce such a service, so called signtiming.

A Sanitizable Signature Scheme with Aggregation
2007A sanitizable signature scheme is a digital signature scheme in which, after generating a signer's signature on a document, specific entities (called sanitizers) can modify the document for hiding partial information. A verifier can confirm the integrity of disclosed parts of the sanitized document from the signature. The sanitizable signature is quite

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.

Aggregated Signatures for Chaining: A Secure Provenance Scheme
2016 IEEE Trustcom/BigDataSE/ISPA, 2016With the explosion of information in daily life, determining the trustworthiness of data has become inevitable. As data from different sources can be used in critical applications such as health-care and military for decision making, data provenance plays an important role to gauge the trustworthiness of data.
