Strongly Unforgeable Ring Signature Scheme from Lattices in the Standard Model
Journal of Applied Mathematics, 2014 In a ring signature scheme, a user selects an arbitrary ring to be able to sign a message on behalf of the ring without revealing the signer’s identity. Whistle-blowers especially find this useful.

ID-based transitive signature schemes without random oracle
Tongxin xuebao, 2010 Based on waters’ signature scheme,the first identity-based transitive signature scheme was proposed and proved secure against attacks in the standard model.Compared with current transitive signature schemes,the unforgeability of the signature’s ...

A Strongly Unforgeable Homomorphic MAC over Integers
Journal of the Korea Institute of Information Security and Cryptology, 2014 Homomorphic MAC is a cryptographic primitive which protects authenticity of data, while allowing homomorphic evaluation of such protected data. In this paper, we present a new homomorphic MAC, which is based on integers, relying only on the existence of secure PRFs, and having efficiency comparable to the practical Catalano-Fiore homomorphic MAC.

Communicating Unforgiveness: How Do Victims Communicate Their Unforgiveness to Their Offenders?
When faced with interpersonal transgressions, some victims maintain unforgiveness towards their offenders. Researchers have identified emotions and cognitions experienced by victims who maintain unforgiveness, but the literature has yet to move beyond investigating the intrapersonal experience of unforgiveness.

Attribute-based alterable threshold ring signature scheme with conspiracy attack immunity
Tongxin xuebao, 2015 Attribute-based cryptography is a generalization and development of the identity-based cryptography,which extends the identity to a set of attributes.In the attribute-based cryptosystem,different members with the same attributes can form a signature ring

User-Mediated Authentication Protocols and Unforgeability in Key Collision
International Journal of Information Security, 2018 This research provides a computational analysis of the ISO 9798-6 standard’s Mechanism 7a authentication protocol. In contrast to typical authentication protocols, ISO 9798-6 mechanism 7a requires user interaction and aims to authenticate data possession instead of identities. Consequently, we introduce a 3-party possession user mediated authentication

Lattice-based verifiable timed signature and application
Tongxin xuebaoAiming at the problem that current verifiable timed signature (VTS) schemes cannot effectively resist the threat of quantum computing attacks, a lattice-based verifiable timed signature (LVTS) scheme was proposed, founded on challenging problems over ...
