A Blockchain-based Access Control Scheme
Xiong Jiang · Journal of Physics Conference Series · 2021
Abstract Access control plays an important role in protecting data privacy. However, traditional access control models such as RBAC, ABAC and UCON need to be built based on a central trusted server. Once the central trusted server is controlled by an adversary, it will pose a serious threat to data security. Therefore, this article proposes a blockchain-based access control scheme, which uses the blockchain to replace the central trusted server and uses smart contracts to complete access. The proposed scheme solves the centralization problem of the traditional access control model. Furthermore, it has been tested on representative equipment, and the experimental results show that the proposed scheme is efficient and feasible.
