Distributed Random Beacon for Blockchain Based on Share Recovery Threshold Signature [PDF]

Sensors, 2022
Random beacons play a crucial role in blockchains. Most random beacons in a blockchain are performed in a distributed approach to secure the generation of random numbers.

Unidirectional Variable Threshold Proxy Re-signature Scheme with Provable Security [PDF]

Jisuanji gongcheng, 2016
In most existing threshold proxy re-signature schemes,threshold value is essentially immutable.However,depending on the significance of re-signature message,the value should be changed dynamically in many practical applications.Based on proxy re ...

Universal composable threshold signature

Tongxin xuebao, 2009
Threshold signature allowed any subset of t parties generating a signature,but that disallowed the creation of a valid signature if fewer than t parties participate in the protocol.Since the security of threshold signature was only con-sidered in a ...

Secure obfuscation for encrypted threshold signatures

Tongxin xuebao, 2020
Aiming at the key leakage security problem of the threshold signature,an encrypted threshold signature functionality was firstly proposed and securely obfuscated.The output of obfuscated circuit could be implemented by any third party without revealing ...

Threshold Lattice-Based Signature Scheme for Authentication by Wearable Devices

Cryptography, 2023
This paper presents a new threshold signature scheme based on Damgaard’s work. The proposed scheme allows for changing the message signature threshold, thereby improving the flexibility of the original Damgaard scheme.

Research Progress and Prospect of Ring Signatures [PDF]

Jisuanji kexue yu tansuo, 2023
As a special group signature, ring signature has been widely used in anonymous voting, anonymous deposit and anonymous transaction because it can not only complete the signature without the cooperation of ring members, but also ensure the anonymity of ...
