SDPP: an intelligent secure detection scheme with strong privacy-preserving for mobile peer-to-peer social network

In this paper, we propose an intelligent secure detection scheme with strong privacy-preserving, called SDPP, for improving routing security and achieving privacy preservation of message in mobile peer-to-peer social network (MP2PSN). Specifically, in the proposed SDPP scheme, each user is granted with a pseudo-ID, a certificate, and its private key corresponding to his similar interests. Based on the cooperative neighbour technique and the homomorphic encryption method, the proposed SDPP scheme cannot only detect and avoid black hole attacks but it also can preserve the message privacy. Through security analysis, we show that the proposed scheme is secure in the MP2PSN scenarios. Moreover, we also discuss how SDPP can achieve the privacy-preservation of message and the evolution of users’ certificates. Both theoretical and simulation results are given to demonstrate the effectiveness of the proposed scheme in terms of black hole detection rate, average Detectreq reporting, and average transmission delay under various scenarios.
