保护个人隐私是未来物联网应用中的一个重要问题，这需要轻量级匿名实体认证解决方案，可以在各种资源受限的物联网设备和小工具上高效执行。现有的匿名证书技术不能很好地适应物联网的设置，尤其是在考虑证书撤销支持的情况下。本文利用动态累加器，提出了一种具有可外包证人更新的轻量级匿名实体认证方案，解决了匿名证书的主要瓶颈问题。我们利用自盲的思想进一步改进了方案的性能，使得证明者的计算完全在双线性映射的紧双线性群上工作。我们的性能评估表明，所提出的方案对于资源受限的设备是很好的。
Preservation of individual privacy is an important issue in future IoT applications, which calls for lightweight anonymous entity authentication solutions that can be executed efficiently upon a wide range of resource-constrained IoT devices and gadgets. Existing anonymous credential techniques are not well fitted to the setting of IoT, and it is especially so when credential revocation support is considered. In this paper, leveraging on dynamic accumulator we propose a lightweight anonymous entity authentication scheme with outsource-able witness update, solving the main bottleneck of anonymous credentials. We further improve the performance of the scheme with the idea of self-blinding, in such a way that the computation by the prover works entirely in the compact bilinear group of bilinear map. Our performance evaluation shows that the proposed schemes are good for resource-constrained devices.
