Security Vulnerabilities of Four Signature Schemes From NTRU Lattices and Pairings

IEEE Access, 2020
Certificateless cryptography solves the certificate management problem in public-key cryptography and the key-escrow problem in identity-based cryptography. Xie et al. proposed a certificateless signature scheme using NTRU lattices.

A secure Certificateless Aggregate Signature Scheme

International Journal of Security and Its Applications, 2016
Aggregate signatures allow n signatures on n distinct messages from n distinct signers to be aggregated into a single signature that convinces any verifier that n signers do indeed sign the n messages, respectively. The major advantage of utilizing aggregate signatures is to address the security of data and save bandwidth and computations in sensor ...

Efficient Certificateless Aggregate Signcryption Scheme with Public Verifiability [PDF]

Jisuanji gongcheng, 2022
Signcryption technology is the foundation of building a network trust system, which can ensure the confidentiality, integrity and verifiability of data.However, when a large number of users perform signcryption at the same time, the verification takes a ...

New Construction of Efficient Certificateless Aggregate Signatures

International Journal of Security and Its Applications, 2014
This paper proposes a novel construction of efficient certificateless aggregate signature (CLAS) scheme. On basis of the computational Diffie-Hellman (CDH) assumption, the proposed scheme can be proven existentially unforgeable against adaptive chosen-message attacks.

Cryptanalysis and Improvement of Three Certificateless Aggregate Signature Schemes [PDF]

Mathematical Problems in Engineering, 2018
The certificateless aggregate signature (CLAS) scheme is a very important data aggregation technique that compresses a large number of signatures from different users into a short signature. CLAS can reduce the total length of a signature and the computational overhead of signature verification and is therefore highly suitable for resource-constrained ...

Cryptanalysis of Compact Certificateless Aggregate Signature Schemes for HWMSNs and VANETs

IEEE Access
Certificateless cryptosystems resolve the critical problems in public-key cryptosystems and identity-based cryptosystems. A certificateless aggregate signature scheme aggregates multiple signatures of multiple signers into a single signature that ...
