An Encryption Based Privacy Preservation Crowd Sensing Scheme with Result Verified

针对群智感知过程中对于任务服务器和工作者的隐私泄露问题,以及感知反馈结果验证过程中的隐私保护问题,借助于边缘节点和加密技术,基于代理重加密和同态加密算法,提出了一种感知结果可验证的隐私保护群智感知方案.该方案通过两轮对感知结果的加密传递,完成对感知结果的隐私保护传送和结果校验.其次,对所提出的方案的处理过程进行详细描述,并分析了这一方案对任务服务器和工作者的隐私保护情况。最后,通过实验验证比较,进一步证明所提出方案的优越性.

To solve the privacy violation problem of task servers and workers in the process of crowd sensing,as well as the privacy protection problem in the verification process of sensing feedback results,a result verified privacy preservation crowd sensing scheme was proposed,using edge nodes and encryption technology,based on proxy re-encryption and homomorphic encryption algorithms.This scheme achieved privacy protection transmission and verification of sensing results through two rounds of encrypted transmission of sensing results.Then in this paper,the detailed process of privacy preservation crowd sensing was given,and the security analysis for every entity was also used to discuss the confidentiality of task and results.At last,several groups of experimental results with brief analyses were given,and used to further demonstrate the superiority of the proposed scheme.
