New Construction of Blind Signatures From Braid Groups
IEEE Access, 2019 A new construction of a blind signature scheme based on braid groups is proposed. In the random oracle model, the proposed scheme is provably unforgeable against chosen message attacks, assuming that the one-more matching conjugate problem in braid ...

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

A probabilistic method for blind multiuser detection using array observations [PDF]
, 1997 In this paper, a blind algorithm for detecting active users in a DS-CDMA system is presented. This probabilistic algorithm relies on the theory of hidden Markov models (HMM) and is completely blind in the sense that no knowledge of the signature ...

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.

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

Determinant-preserving blind signatures from Hadamard-type t-Jacobsthal–Leonardo sequences [PDF]
Notes on Number Theory and Discrete MathematicsIn this paper, we introduce a new class of sequences called the termed Hadamard-type t-Jacobsthal-Leonardo sequence which is generated by applying a Hadamard-type product to the characteristic polynomials of the t-Jacobsthal and Leonardo sequences.

IET Biometrics, 2022 Signing a document or a cheque by hand or using a stored image‐based signature is known to be a valid method for authentication and authorisation by the signer. However, signature forging has advanced to replicate exactly how a signature looks, which can

Implementation strategies for hyperspectral unmixing using Bayesian source separation [PDF]
, 2010 Bayesian Positive Source Separation (BPSS) is a useful unsupervised approach for hyperspectral data unmixing, where numerical non-negativity of spectra and abundances has to be ensured, such in remote sensing.

Blind Hyperspectral Unmixing Using Autoencoders: A Critical Comparison
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Deep learning (DL) has heavily impacted the data-intensive field of remote sensing. Autoencoders are a type of DL methods that have been found to be powerful for blind hyperspectral unmixing (HU). HU is the process of resolving the measured spectrum of a
