Problems solved by technology

[0005] The existing technology has not yet formed a complete set of supervision and certification process for networked equipment, so the application of existing networked equipment in each link is still in a state of mutual independence, and the cost of actual implementation is higher, which is directly The popularity rate of security certification has been reduced, and there are potential security risks for the actual application of networked devices

Embodiment Construction

[0049] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0050] The present invention designs a blockchain-based networked device supervision and authentication method and system, which is used to realize the supervision and certification of networked devices for smart devices or IT / OT devices as networked devices; in practical applications, such as figure 1 As shown, for the equipment manufacturers, regulatory agencies, and user organizations of networked equipment, the specific design equipment manufacturers include the manufacturer's blockchain nodes corresponding to the blockchain, and the IBC key management infrastructure and encryption and decryption modules corresponding to the equipment manufacturers. ; Among them, the IBC key management infrastructure includes the public parameter service of the encryption service adopted by the equipment manufacturer, and the manufact...

Abstract

The present invention relates to a networked device supervision and authentication method and system based on block chain technology, which introduces block chain as storage, realizes IBC key infrastructure services for distributed user registration with a shared negotiation mechanism, and can more efficiently guarantee identity identification Uniqueness, improve system stability and openness, meet the requirements of full life cycle management of devices such as registration and identity authentication for device manufacturers, regulatory agencies, and user agencies in the production, sales, and use of large-scale smart terminals and networked devices Security guarantee, the entire design scheme does not rely on a single agency, and the data can be checked, traced, and difficult to tamper with, effectively ensuring the security of the actual application of networked devices.

Description

technical field [0001] The invention relates to a block chain-based networked equipment supervision and certification method and system, belonging to the technical field of networked equipment supervision and certification. Background technique [0002] In order to reduce the complexity of key and certificate management in the public key system, Adi Shamir, an Israeli scientist and one of the inventors of the RSA algorithm, proposed the concept of Identity-Based Cryptography in 1984. The identification password uses the user's identification (such as email address, mobile phone number, QQ number, etc.) as the public key, omitting the process of exchanging digital certificates and public keys, making the security system easy to deploy and manage, and very suitable for end-to-end offline secure communication , Cloud data encryption, attribute-based encryption, policy-based encryption in various occasions. In 2008, the identification encryption algorithm officially obtained th...
