摘要
针对基于属性的访问控制模型存在的安全性问题,笔者提出了基于区块链技术的安全访问控制机制。该机制将区块链技术与基于属性的访问控制相结合,利用区块链去中心化、分布式等特点,在实现匿名访问控制的基础上实现了访问控制策略管理。分析表明,区块链对策略的存储管理能够防止出现客体资源恶意拒绝访问的情况。
Aiming at the security problems of the attribute-based access control,the paper proposes a secure access control mechanism based on blockchain.This mechanism combines blockchain technology with attribute-based access control,and utilizes the characteristics of blockchain decentralization and distribution to realize the management of access control policies on the basis of achieving anonymous access control.The analysis shows that the blockchain’s storage management of policies can prevent the object resources from maliciously denying access.
