Smart home security access control method and device and storage medium

Abstract

The invention discloses a smart home security access control method and device and a storage medium, a main body sends an access request to an access control contract, the access control contract judges whether the access request sent by the main body is a normal access request, if yes, an access result is stored in a hyperledger structure classification ledger, and if not, the access result is stored in a hyperledger structure classification ledger; the subject sends a connection request to the object; the object calls the access control contract to query the access result, and makes an access decision according to the access result; and the credit management center updates the trust capability tokens of the subject and the object. The problem of security risk caused by the fact that the block chain network is attacked by the DDOS is solved.

Description

technical field [0001] The invention relates to Internet of Things technology, in particular to a smart home security access control method, device and storage medium. Background technique [0002] Smart home is a typical IoT application scenario. Smart home systems aim to improve the quality of life by providing various automated, interactive and comfortable services, such as providing medical services to family members, remotely controlling devices through mobile phones, emails, etc. The user feels a comfortable temperature. At the same time, however, this convenience can create the potential for malicious cyber-attacks, posing risks to the safety and privacy of residents. [0003] In the face of security issues in smart home systems, access control technology can prevent attackers from accessing and modifying data in devices, and plays an important role in the protection of residents' resources and information. In addition, traditional access control models, such as ac...

Problems solved by technology

However, this method cannot guarantee the fairness and security of the authorization server itself, and has disadvantages such as single point of failure, difficult expansion, low reliability, and low throughput.

[0007] 2) Lack of security: When some malicious nodes launch DDOS attacks on the blockchain network by repeatedly sending access requests, it will cause the blockchain network to be blocked

[0008] 3) Lack of privacy: Since the access records of the equipment are stored on the blockchain ledger, malicious nodes can use this information to infer residents’ daily activities
