Trustworthy Device Pairing for Opportunistic Device-to-Device Communications in Mobile Crowdsourcing Systems

Abstract

Mobile Crowdsourcing System is an emerging service paradigm base on numerous personal smart devices, where the Device-to-Device communication among opportunistically encountered participating devices is an indispensable part of task allocation, file transmission and data collaboration. Considering that participating devices are privately held and opportunistically encountered, we design the Trustworthy Device Pairing (TDP) scheme that realizes user-transparent sharing secret key negotiation and reliable peer device determination for trustworthy spontaneous D2D transactions. TDP is demonstrated to be effective based on our proof-of-concept implementation, and a further evaluation on efficiency will be conducted.
