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.
