RPC-Chain:基于信誉机制与受控PRE的众包模型链OA北大核心
RPC-Chain:crowdsourcing model chain based on reputation mechanism and controlled PRE
为解决众包面临的信任问题、不对称贡献与收益关系以及数据安全性共享等挑战,提出一种基于信誉模型与受控代理重加密(PRE)的众包模型链,即RPC-Chain.RPC-Chain基于超级账本Fabric,将众包模型的交易流程抽象化.首先,完善信誉机制提高系统整体的效率与公平;其次,引入受控代理重加密以确保数据安全共享服务;最后,使用Fabric搭建众包区块链仿真平台并进行了相关测试.实验表明,该方案在模型设计、数据安全加密共享和信誉模型的激励效果等方面显示出一定优势.
This paper addressed the challenges of trust issues,asymmetric contribution and benefit relationships,and data se-curity sharing in crowdsourcing by proposing an RPC-Chain,a crowdsourcing model chain based on a reputation model and proxy re-encryption(PRE).RPC-Chain abstracted the transaction process of the crowdsourcing model based on Hyperledger Fabric.Firstly,it improved the reputation mechanism to enhance the overall efficiency and fairness of the system.Secondly,it introduced proxy re-encryption to ensure secure data sharing services.Finally,it built a crowdsourcing blockchain simulation platform using Fabric,and conducted related tests.The experiments demonstrate that the proposed scheme shows certain ad-vantages in model design,secure data encryption sharing,and the incentive effect of the reputation model.
