In mobile internet of things (MIoTs), it is very important how to protect the identities of terminal devices so as to implement the privacy security. On the one hand, if a malicious MIoT device issues its false data under full privacy protection, then this device may abuse the privacy protection function to arbitrarily issue its false data, and it can not be disclosed. Therefore, in this paper we propose a traceable identity-based ring signature (TIBRS) scheme with constant size for protecting and tracing the identities of MIoT devices. In our ...
