Trusted traceability method and system, and storage medium

Abstract

The invention discloses a trusted traceability method and system based on blockchain, and a storage medium, and belongs to the field of open use of security data and security results. The method comprises the steps: establishing an initial database, wherein the initial database is open, and the security capability type and the security capability of the initial database can be dynamically expanded; constructing a security information chain in a local area network, carrying out data uplink, process uplink and capability uplink on source data stored in the initial database, constructing a privacy model, and carrying out privacy calculation on the uplink data; credibly opening the security data after privacy calculation, expanding the security data, and upgrading the security data into a security capability resource pool. The method further enriches the security data, process and capability of the uplink, constructs an open tenant defense alliance in the extensive local area network, realizes sharing of security resource pool customer security protection results in the local area network, and is suitable for the field of multi-target customer group security of governments, enterprises and the like.

Description

technical field [0001] The invention belongs to the field of transmission of H04L digital information, in particular to the field of open use of security data and security results, and in particular to a blockchain-based trusted traceability method, system, and storage medium. Background technique [0002] With the continuous development of science and technology, the attack methods of network security and data security are also constantly improving. The traditional cyberspace security protection system and data security protection tools are mainly static and cannot realize effective linkage between components. Defending alliances cannot be effectively formed. At the same time, the cyber attackers have formed a certain scale of attack surface. While sharing tools and technologies, they have also reached a certain consensus on attack data, resulting in a passive situation where the defenders face each other. [0003] For example, the data of the target customer is unique, th...

[0002] With the continuous development of science and technology, the attack methods of network security and data security are also constantly improving. The traditional cyberspace security protection system and data security protection tools are mainly static and cannot realize effective linkage between components. Unable to effectively form a defensive alliance

At the same time, the cyber attackers have formed a certain scale of attack surface. While sharing tools and technologies, they have also reached a certain consensus on attack data, resulting in a passive situation where the defenders face each other.

[0003] For example, the data of the target customer is unique, that is, when the target customer uses it, it has a certain degree of security, but when the auth
