To　realize　the　identity　privacy,　credential　revocation,　credit　incentive　features　and　mediate　the　contradiction　between　the　identity　tracking　of　malicious　users　and　the　privacy　protection　of　honest　users　in　a　mobile　crowdsensing　system,　a　mobile　crowdsensing　scheme　with　strong　privacy-preserving　is　proposed.　Based　on　threshold　cryptography,　the　new　scheme　distributes　the　identity　tracking　capability　of　anonymous　users　to　multiple　entities,　which　guarantees　that　multiple　trackers　can　cooperatively　reveal　the　real　identity　of　users.　Pointcheval-Sanders　signature　and　Camenisch-Lysyanskaya　accumulator　based　on　Rivest-Shamir-Adleman　assumption　are　combined　to　realize　efficient　and　secure　revocation　of　credentials.　The　privacy-preserving　credit　management　mechanism　is　constructed　by　adopting　the　Pointcheval-Sanders　signature.　The　security　and　experimental　analysis　of　the　scheme　is　carried　out.　The　experimental　results　show　that　the　scheme　not　only　meets　the　security　requirements,　but　also　has　feasibility　in　practical　deployment.　©　2021,　Editorial　Department　of　Journal　of　Beijing　University　of　Posts　and　Telecommunications.　All　right　reserved.
