| 摘 要： | 针对当前社会物联网可信服务管理中存在的中心化程度高、交易不透明和易受攻击等问题，提出了一种基于区块链的社会物联网可信服务管理框架。该框架通过区块链的去中心化特性在服务请求者和服务提供者之间直接建立信任关系，利用智能合约产生并管理新的交易，实现交易过程透明化并减少管理维护成本。同时，区块链的共识机制可用于交易验证并防范恶意攻击和篡改，减少网络攻击和恶意节点的欺骗。最后，分析了该框架在实际构建中面临的主要挑战。

| Abstract: | To cope with current problems of trusted services management in social internct of things (SIoT),such as high degree of centralization,non-transparent transactions,vulnerability and so on,a framework of trusted services management based on blockchain in SIoT was proposed.This framework established the trusted relationship between service requesters and service providers directly by using decentralization of blockchain,then it produced and managed new transactions through smart contracts to realize transparency and reduce the cost of management.At the same time,the consensus mechanism of blockchain could be used for verifying transactions and preventing malicious attacks in order to reduce network attacks and malicious node spoofing.Finally,the main challenges which the framework would face in actual constructions were analyzed. |
