Abstract

Abstract:

Compared with centralized system, distributed system has difficult in reaching consensus in the system. Therefore, distributed systems are greatly limited in application of information storage. With the advent of the blockchain and its further research, a more reliable implementation is given for establishing consensus in distributed systems. In this paper, we propose a distributed public key scheme based on blockchain technology, which shares the key storage responsibility through the nodes in the blockchain network. By splitting storage system into constituent nodes in the network, it can provide better response performance and anti-interference capability than the traditional centralized public key system. For the shortcomings that have appeared in the application of the blockchain system in the field of virtual currency, after analyzing the impact of these defects on the management of the public key, some blockchain system is avoided by some improvements. At the end of the article, some common attacks on public-key systems are analyzed. The results show that the system has a strong anti-jamming effect on the aggressors' System security.
