Abstract

The invention discloses an extensible access control method oriented to fog computing. The method adopts a linear secret sharing matrix as an access structure to realize attribute-based access control, uses fog nodes as edge service nodes, and reasonably distributes encryption and decryption in access control. computing to reduce the computing overhead of end users in access control. Moreover, the present invention can add new legal members to form a new access policy on the basis of maintaining the original access policy, and can also detect whether the access user has tampered with the original data when uploading the new access policy, and realizes the original data. Integrity protection.

Description

technical field [0001] The invention belongs to computer application technology, and in particular relates to an extensible access control method oriented to fog computing. Background technique [0002] Cloud computing technology brings users unprecedented computing power and almost unlimited storage space. Users can use the cloud platform to realize a series of massive data analysis, processing, storage and other work. However, because the core network where the cloud platform server is located is often far away from the end users, this has led to the inability of cloud computing to provide reliable real-time responses in practical applications, especially in applications that require high real-time requirements. Bottlenecks that limit cloud computing applications. Among them, fog computing, as a typical edge computing model, has gradually become a research hotspot in recent years. Fog computing has the advantages of low latency, mobility, and distribution, so it can well...
