A Solidity implementation of TAVS
Frontiers in Blockchain, 2023 We present a Solidity smart contract implementation of the TAVS e-voting protocol. The Two Authorities Electronic Voting Scheme (TAVS) is a voting scheme that achieves universal verifiability with a reduced time-complexity both for the elector and the ...

Lattice-Based Blind Signatures: Short, Efficient, and Round-Optimal
IACR Cryptology ePrint Archive, 2023 We propose a 2-round blind signature protocol based on the random oracle heuristic and the hardness of standard lattice problems (Ring/Module-SIS/LWE and NTRU) with a signature size of 20 KB.

Two-Party Cooperative Blind Signature Scheme Based on SM9 [PDF]
Jisuanji gongcheng, 2023 In the existing SM9 blind signature scheme，the signature private key is leaked easily and the signature power is centralized，which are problematic.Hence，a two-party collaborative blind signature scheme based on SM9 is proposed.The Key Generation Center ...

Quantum-secure message authentication via blind-unforgeability [PDF]
, 2020 Formulating and designing unforgeable authentication of classical messages in the presence of quantum adversaries has been a challenge, as the familiar classical notions of unforgeability do not directly translate into meaningful notions in the quantum ...

A New Post-Quantum Blind Signature From Lattice Assumptions
IEEE Access, 2018 At present, several post-quantum cryptosystems have been proposed, and lattice-based cryptography is the main candidate. Especially in the direction of digital signatures, there are now many practical lattice-based signature schemes. However, there exist

Post-Quantum Secure Identity-Based Proxy Blind Signature Scheme on a Lattice
Entropy, 2023 Blind signatures have been widely applied when privacy preserving is required, and the delegation of blind signature rights and a proxy blind signature (Proxy-BS) become necessary when the signer cannot sign.

Sparsity and morphological diversity for hyperspectral data analysis [PDF]
, 2010 Recently morphological diversity and sparsity have emerged as new and effective sources of diversity for Blind Source Separation. Based on these new concepts, novelmethods such as Generalized Morphological Component Analysis have been put forward ...

CAUDHT: Decentralized Contact Tracing Using a DHT and Blind Signatures
IEEE Conference on Local Computer Networks, 2020 Contact tracing is a promising approach to combat the COVID-19 pandemic. Various systems have been proposed to automatise the process. Many designs rely heavily on a centralised server or reveal significant amounts of private data to health authorities ...

Partial blind signature scheme based on SM9 algorithm
网络与信息安全学报, 2021 Ordinary digital signatures have many deficiencies in effectively protecting users' privacy, and signature repudiation and tracking occur from time to time. In order to solve the above problems, a partial blind signature scheme based on the SM9 algorithm
