Blockchain-Assisted Secure Device Authentication for Cross-Domain Industrial IoT

Industrial Internet of Things (IIoT) is considered as one of the most promising revolutionary technologies to prompt smart manufacturing and increase productivity. With manufacturing being more complicated and sophisticated, an entire manufacturing process usually involves several different administrative IoT domains (e.g., factories). Devices from different domains collaborate on the same task, which raises great security and privacy concerns about device-to-device communications. Existing authentication approaches may result in heavy key management overhead or rely on a trusted third party. Thus, security and privacy issues during communication remain unsolved but imperative. In this paper, we present an efficient blockchain-assisted secure device authentication mechanism $\textsf{BASA}$ for cross-domain IIoT. Specifically, consortium blockchain is introduced to construct trust among different domains. Identity-based signature (IBS) is exploited during the authentication process. To preserve the privacy of devices, we design an identity management mechanism, which can realize that devices being authenticated remain anonymous. Besides, session keys between two parties are negotiated, which can secure the subsequent communications. Extensive experiments have been conducted to show the effectiveness and efficiency of the proposed mechanism.This work was supported in part by the National Key Research and Development Program of China under Grant 2018YFB0803405, in part by the National Natural Science Foundation of China under Grant 61972039, Grant 61932016, and Grant 61872041, in part by the Beijing Natural Science Foundation under Grant 4192050, in part by China National Funds for Distinguished Young Scientists under Grant 61825204, in part by the Beijing Outstanding Young Scientist Program under Grant BJJWZYJH01201910003011, and in part by the Beijing National Research Center for Information Science and Technology (BNRist) under Grant BNR2019RC01011
