Linkable Ring Signature Scheme Using Biometric Cryptosystem and NIZK and Its Application
Security and Communication Networks, 2021 Biometric encryption, especially based on fingerprint, plays an important role in privacy protection and identity authentication. In this paper, we construct a privacy-preserving linkable ring signature scheme. In our scheme, we utilize a fuzzy symmetric

White-Box Traceable Ciphertext-Policy Attribute-Based Encryption in Multi-Domain Environment
IEEE Access, 2019 In a ciphertext-policy attribute-based encryption (CP-ABE) system, the decryption keys are only related to attributes shared by multiple users and do not contain any identity information of their original holders.

Linkable Ring Signatures from Linear Feedback Shift Register [PDF]
, 2007 Linkable ring signatures can simultaneously provide the properties of anonymity, spontaneity as well as linkability. Linear feedback shift register (LFSR) sequence can be used to shorten the representation of elements in a field. This paper proposes an LFSR-based linkable ring signature scheme, whose main computation operations are performed in base ...
