摘要
远程证明是构建可信网络的核心。但是,当前的远程证明模型仅面向有中心的网络,存在网关中心化、决策单点化的问题,并不适用于去中心的场景。针对去中心分布式网络环境中计算节点无法进行远程证明的问题,借鉴区块链的思想,提出了一种基于区块链的远程证明模型(Remote Attestation Based on blockchain,RABBC),并重点描述了模型框架、区块链核心结构和协议过程。分析表明,RABBC具有去中心化、可追溯、匿名、不可篡改的安全特性,并具备较高的效率。
Remote attestation is the core of constructing the trusted network.However,current remote attestation model only looks on centralized network,in which there are some problems,such as centralized gateway and decision by single point,causing that it is not suitable to use this model in decentralized situation.Aiming at the problem that the computing node cannot execute remote attestation in the environment of centralized distributed network,by drawing lessons from the thought of blockchain,this paper proposed a remote attestation model based on blockchain（RABBC）,and focused on model frame,core structure of blockchain and protocol process.The analysis shows that RABBC has the safe characteristics of decentralization,traceability,anonymity,non-tampering,and it is efficient.
