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

An Aggregate Signature Scheme with Constant Pairing Operations
2008 International Conference on Computer Science and Software Engineering, 2008We propose a new aggregate signature scheme from bilinear pairings. It requires constant pairing operations in the verification and the size of aggregate signature is independent of the number of signers. In the public key infrastructure (PKI) setting, it is the first aggregate signature scheme with these properties.

Three attacks of certificateless aggregate signature scheme
Proceedings of the ACM Turing Celebration Conference - China, 2019After in-depth research, this paper finds that there are three types of attacks in the existing certificateless aggregate signature scheme. For these three types of attacks, this paper gives detailed attack steps for specific schemes, analyzes the reasons for the existing attacks and proposes improvement measures. This paper provides ideas for the next

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.

On the Security of an Identity-Based Aggregate Signature Scheme
22nd International Conference on Advanced Information Networking and Applications - Workshops (aina workshops 2008), 2008In ACISP 2006, Paterson and Schuldt proposed a provably secure identity-based signature scheme. Not long after that, the same authors claimed that their proposed scheme above also allows a form of aggregation in which the multiple signatures from the different signers on a single message can be aggregated into a single signature with a more efficient ...

On security of a Certificateless Aggregate Signature Scheme. [PDF]
IACR Cryptol. ePrint Arch., 2012 Aggregate signatures are useful in special areas where the signatures on many different messages generated by many different users need to be compressed. Recently, Xiong et al.

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.

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 ...
