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

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 ...

Improved heterogeneous aggregation signature scheme
2020 IEEE 9th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2020The heterogeneous aggregate signcryption scheme can authenticate the signatures of multiple messages, thereby ensuring the authenticity of the messages. And this technology also solves the communication problem under different cryptosystems. However, most of the current schemes have hidden dangers of insecurity, and the signcryption may be forged ...

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 ...

Aggregate Signature Consensus Scheme Based on FPGA
2019With the rapid development of cryptocurrency, such as the Bitcoin, block chain technology, as the bottom technology of Bitcoin, has been widely concerned by researchers. Block chain has the characteristics of decentralization, anonymity and non-tampering, which realizes the transformation from social trust to machine trust.

Comparing two pairing-based aggregate signature schemes
Designs, Codes and Cryptography, 2009This paper describes detailed security and performance comparisons of two aggregate signature schemes. The first (BGLS), due to \textit{D. Boneh, C. Gentry, B. Lynn} and \textit{H. Shacham} [Eurocrypt 2003, Lect. Notes Comput. Sci. 2656, 416--432 (2003; Zbl 1038.94553)], uses bilinear pairings and has a reductionist security proof assuming the random ...

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 ...

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 ...

MQ Aggregate Signature Schemes with Exact Security Based on UOV Signature
2020Multivariate public key cryptography which relies on multivariate quadratic (MQ) problem is one of the main approaches to guarantee the security of communication in the post-quantum world. In this paper, we focus mainly on the yet unbroken (under proper parameter choice) Unbalanced Oil and Vinegar (UOV) scheme, and discuss the exact security of it ...
