Measurement data safety protection method

Abstract

The invention belongs to the field of information safety, and particularly relates to a measurement data safety protection method, which comprises the following steps of: 1, user authentication: when a user accesses a data resource for the first time, firstly applying a safety certificate from a safety certificate authority so as to prove the identity of the user when the user accesses the data resource, safety assurance is carried out on malicious access which does not obtain the safety certificate by adopting a mode of denying to access data resources; and step 2: domain positioning: when a user passing identity authentication accesses data resources, an access request Req (SAVt, RAVm, EAVn, AAVk) is forwarded to a domain positioning server, the domain positioning server analyzes a subject attribute and a resource attribute, the subject attribute and the resource attribute respectively correspond to the SAVt and the RAVt, and whether local access or cross-domain access is determined according to an analysis result. According to the method, an attribute-based access control model is adopted, the problems of user authentication, domain positioning, access decision and module association are solved, the data safety in a big data environment can be effectively protected, and quick decision and efficient access can be realized.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a measurement data security protection method. Background technique [0002] With the rapid development of cloud computing, the Internet of Things, and the mobile Internet, the scale of data that needs to be collected, processed, and managed has grown rapidly, and data information has grown explosively. As a national basic energy facility, the power industry provides power support for the development of the national economy. , is closely related to social development and people's lives, and is an important condition for the healthy, stable, sustained and rapid development of the national economy. With the development of the smart grid, the data and information in the power system will become more complex, the amount of data and information will increase exponentially, and the correlation between various types of information will be closer. [0003] Metering is one...

Problems solved by technology

The access to data resources has also changed from single-user and single-host access to multi-user and multi-data domain data access, which leads to the problem of complex user and multi-data resource domain access in the big data service environment, but this also affects data from another aspect. Security poses new requirements and challenges. Traditional data security protection methods are gradually difficult to meet actual needs and need to be improved.
