BAAR: A framework for blockchain-based anonymous and revocable user authentication scheme. [PDF]
PLoS ONEBlockchain-based systems increasingly require authentication mechanisms that simultaneously preserve user privacy, support accountability, and enable efficient credential revocation. However, most existing anonymous authentication schemes rely on pairing-

Logarithmic-Size Post-Quantum Linkable Ring Signatures Based on Aggregation Operations [PDF]
EntropyLinkable ring signatures are a type of ring signature scheme that can protect the anonymity of signers while allowing the public to verify whether the same signer has signed the same message multiple times.

EKV-VBQ: Ensuring Verifiable Boolean Queries in Encrypted Key-Value Stores [PDF]
SensorsTo address the deficiencies in privacy-preserving expressive query and verification mechanisms in outsourced key-value stores, we propose EKV-VBQ, a scheme designed to ensure verifiable Boolean queries over encrypted key-value data.

Fail-Stop Ring Signature Scheme Based on Certificateless Cryptosystem [PDF]
Jisuanji gongcheng, 2020 Fail-stop group signature schemes can prevent opponents with strong compute power from counterfeiting signatures,and thereby implement privacy protection for users.On the basis of the fail-stop group signature scheme,this paper designs a fail-stop ring ...

Security Analysis of An Efficient Identity-Based Signature Scheme [PDF]
Jisuanji gongcheng, 2018 HUANG Yicai et al (Journal of Cryptologic Research,No.5,2017) proposes an efficient identity-based signature scheme,which uses a hybrid game approach to prove that the scheme is strongly unforgeable in a standard model,and its security depends on the ...
