一种基于组合公钥的密钥派生方案
A Key Derivation Scheme Based on Combined Public Key
摘要
Abstract
In order to improve the security in a single-key signing system,a key derivation scheme based on combined public key was designed.Firstly,a new key generation scheme was proposed for the collu-sion attack in the combined public key system.By introducing the prime coefficient,the mapping coeffi-cient matrix reached the full rank,and the private keys were less than the rank and linearly independent. Secondly,the resistance of the scheme to the linear collusion attack,choice collusion attack and random collusion attack was analyzed.Finally, the scheme was implemented in Python and its performance was compared with that of traditional ECDSA.关键词
