在移动物联网（MIoT）中，如何保护终端设备的身份以实现隐私安全非常重要。一方面，如果恶意MIoT设备在充分的隐私保护下发布其虚假数据，那么该设备可能会滥用隐私保护功能，任意发布其虚假数据，并且无法公开。因此，在本文中，我们提出了一种具有恒定大小的可追踪的基于身份的环签名（TIBRS）方案，用于保护和追踪MIoT设备的身份。在我们提出的方案中，MIoT 设备可以通过可追踪的基于身份的环签名匿名发布其数据，从而保护其身份。另一方面，如果需要追踪其身份，那么受信任的第三方（私钥生成器）可以在这些 MIoT 设备生成的签名上追踪其身份。基于相关的安全模型，我们提出的方案被证明对标准模型中的计算 Diffie-Hellman 假设具有安全性降低，其中我们的方案具有足够的安全性来保护 MIoT 设备的身份的匿名性。与其他相关工作相比，我们的方案在 MIoT 设备上需要更少的计算开销，从而生成恒定大小的签名。
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 proposed scheme, the MIoT devices can anonymously issue their data by traceable identity-based ring signatures, where their identities are protected. On the other hand, if their identities need to be traced, then a trusted third party (private key generator) can trace the identities of these MIoT devices on their generated signatures. Based on the related security model, our proposed scheme is proved to have a security reduction to the computational Diffie-Hellman assumption in the standard model, where our scheme has the anonymity with enough security to protecting the identities of MIoT devices. Compared with other related works, our scheme requires less computational overhead on MIoT devices, which generates constant size signatures.
