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

An efficient certificateless aggregate signature without pairing
International Journal of Electronic Security and Digital Forensics, 2018Aggregate signature scheme enables an algorithm to combine n signatures of n distinct messages from n users into a single short signature. The resulting aggregate signature can convince the verifier that the n users indeed sign the n messages. Since it greatly reduces the total signature length and verification cost, this primitive is useful especially

Privacy-Protected Certificateless Aggregate Signature Scheme in VANET
2019 11th International Conference on Wireless Communications and Signal Processing (WCSP), 2019We propose a certificateless aggregate signature (CLAS) scheme for privacy protection based on the certificateless public key cryptosystem and aggregate signature aiming at the common problems of communication security and efficiency in vehicular ad hoc network (VANET).

Certificateless Sequential Aggregate Signature Scheme on NTRU Lattice
Chinese Journal of Electronics, 2019Having the advantages of certificateless signature and the aggregate signature at the same time, certificateless aggregate signature has been widely applied in e-business, e-government and software security since it was proposed in 2007. Although a number of certificateless aggregate signature schemes have been proposed, all of them are based on the ...

A comment on efficient certificateless aggregate signature scheme
2017 International Conference on Computing, Communication and Automation (ICCCA), 2017Certificateless signature scheme provides the solution of key escrow problem inherit in ID based public key cryptography. Aggregate signature allows aggregating of n signature in one single short signature which is very efficient in ad-hoc networks, PDA, mobile computation and more.

An efficient certificateless aggregate signature with constant pairing computations
Information Sciences, 2013An 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 savings.

Security Anlysis of Certificateless Aggregate Signature Scheme in VANETs
2019 12th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2019Certificateless aggregate signature (CLASS) scheme which combines on certificateless signature and aggregation signature solves the identity-based (ID) public key infrastructure (PKI)'s key escrow problem, the PK problem of traditional PKI. So, CLASS schemes can be applied in many fields to solve the privacy problem and security problem, for example in
