Expanders and right-angled Artin groups
, 2021 The purpose of this article is to give a characterization of families of expander graphs via right-angled Artin groups. We prove that a sequence of simplicial graphs $\{\Gamma_i\}_{i\in\mathbb{N}}$ forms a family of expander graphs if and only if a ...

ID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings [PDF]
, 2004 In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al.

Limited Verifier Signature from Bilinear Pairings [PDF]
, 2004 Motivated by the conflict between authenticity and privacy in the digital signature, the notion of limited verifier signature was introduced [1]. The signature can be verified by a limited verifier, who will try to preserve the privacy of the signer if the signer follows some specified rules. Also, the limited verifier can provide a proof to convince a

Certificateless strong designated verifier multi-signature
Tongxin xuebao, 2016 In order to satisfy the application requirements in the fields of judicial administration,e-government,etc.,the definition and security model for certificateless strong designated verifier multi-signature were proposed.Then,the first certificateless ...

A Provably-Secure Outsourced Revocable Certificateless Signature Scheme Without Bilinear Pairings
IEEE Access, 2018 Certificateless public key cryptosystem (CLPKC) is a desirable cryptographic system because it refrains from both certificate management and key escrow. In CLPKC, how to revoke a misbehaving or compromised user is an important issue.

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.

On $5$-manifolds with free fundamental group and simple boundary links in $S^5$
, 2017 We classify compact oriented $5$-manifolds with free fundamental group and $\pi_{2}$ a torsion free abelian group in terms of the second homotopy group considered as $\pi_1$-module, the cup product on the second cohomology of the universal covering, and ...
