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.

Aggregatable Certificateless Designated Verifier Signature [PDF]
IEEE Access, 2020 In recent years, the Internet of Things (IoT) devices have become increasingly deployed in many industries and generated a large amount of data that needs to be processed in a timely and efficient manner. Using aggregate signatures, it provides a secure and efficient way to handle large numbers of digital signatures with the same message. Recently, the

Certificateless-based efficient aggregate signature scheme with universal designated verifier
Tongxin xuebao, 2015 The security model of the certificateless aggregate signature scheme with universal designated verifier was studied,and then a certificateless aggregate signature scheme with universal designated verifier using bilinear pairings was proposed.In the ...

Certificateless Linkable Ring Signature Scheme
IEEE Access, 2020 Ring signature is an anonymous signature that both authenticates the message and protects the identity information of the signer. It is suitable for scenarios such as anonymous network access, online auctions, etc. However, there is a problem in a regular ring signature scheme.

IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...

Certificateless signature scheme without bilinear pairings
Tongxin xuebao, 2012 To solve the key escrow problem inherited in ID-based cryptography and the complex certificate management problem of traditional certification-based public key cryptosystem,Al-Riyami and Paterson proposed the novel concept of certificateless public key ...
