摘要：In recent years, IoT devices have been widely used in the newly-emerging technologized such as crowd-censoring and smart city. Authentication among each IoT node plays a central role in secure communications. Generally, zero-knowledge identification scheme enables one party to authenticate himself without disclosing any additional information. However, a zero-knowledge based protocol normally involves heavily computational or interactive overhead, which is unaffordable for lightweight IoT devices. In this paper, we propose a modified zero-knowledge identification scheme based on that of Silva, Cayrel and Lindner (SCL, for short). The security of our scheme relies on the existence of a commitment scheme and on the hardness of ISIS problem (i.e., a hardness assumption that can be reduced to worst-case lattice problems). We present the detail construction and security proof in this paper. © Springer Nature Switzerland AG 2018.
