Embodiment Construction

[0046] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0047] Such as figure 1 As shown, the security control system applied to the smart grid wireless sensor network and cloud computing includes a data discrimination module, an access control module and a data encryption module set in the cloud. The data discrimination module is connected to the wireless sensor network terminal, and the data discrimination module One output of the module is connected to the user end through the access control module, and the other output is connected to the user end through the data encryption module.

[0048] The data discrimination module is used to receive the sensing data obtained from the wireless sensor network end, classify the importance of the sensing data, send non-important data to the access contro...

Abstract

The invention discloses a safety control system and method applied to a smart power grid wireless sensor network and cloud computing. The safety control method comprises the steps that data are collected; whether the data are important data or unimportant data is judged; access control is performed to guarantee that the unimportant data are only transmitted to a user with access right; the important data are encrypted according to an encryption algorithm obtained through search, and therefore it is guaranteed that the important data are not illegally tampered or peeked at. According to the safety control system and method applied to the smart power grid wireless sensor network and cloud computing, an access control module is used for guaranteeing that the unimportant data are transmitted to the user with the access right; an access tree structure is adopted, so that complexity is low; the important data are encrypted through the encryption algorithm obtained through search, as a result, a third party can not know or tamper encrypted data content, it can be effectively avoided that sensing data are tampered and peeked at by the third party in the transmission process, and the integrity and confidentiality of the data are guaranteed. Due to the adoption of two safety strategies, the safety control system and method have the advantages of being high in flexibility and extendibility and the like.

Description
