融合区块链的算力网络信任评估与保障方案研究

Blockchain⁃based trust evaluation and guarantee scheme for computing power network

算力网络是通过网络承载、传递泛在计算服务,实现计算、网络融合一体化的新型网络架构。为实现安全可信的算力共享,借助区块链技术,提出了融合区块链的算力网络架构,并基于该架构设计了包含用户身份认证机制、算力服务注册机制、交易机制、信誉评估机制的信任评估与保障方案。仿真结果表明,该方案可为算力网络的算力资源共享提供安全可信保障。

The computing power network is a new network architecture for realizing computing and network integration by carrying and delivering ubiquitous computing services in the network.To realize safe and reliable computing power sharing,a computing power network architecture integrating blockchain is proposed with the blockchain technology.Under this architecture,a trust evaluation and guarantee scheme,including mechanism of the user identity registration,the computing power registration and perception,and the transaction and reputation evaluation,is designed.Simulation results show that the scheme can provide a safe and credible guarantee for the computing power resource sharing in the computing power network.
