Communication method of power asset management master station system and RFID (radio frequency identification device) terminal

Abstract

The invention relates to a communication method of a power asset management master station system and an RFID terminal. The method guarantees the identity legitimacy of a client by providing bidirectional authentication for the RFID terminal and the management master station system and encrypting private data and through digital signatures; a terminal layer is mainly composed of the RFID mobile terminal and an RFID reading and writing module and mainly achieves the operations such as field installation, label information inquiry and equipment checking of power grid equipment labels. The communication method of the power asset management master station system and the RFID terminal can guarantee the communication safety between the power asset management master station system and the RFID terminal; two communicating parties can establish safe communication channels therebetween for data transmission only by holding key certificates and being authorized.

Description

technical field [0001] The invention relates to a secure communication method, in particular to a communication method between a power asset management master station system and an RFID terminal. Background technique [0002] As one of the most important components of power enterprise assets, power assets are an important guarantee for the completion of power production and operation tasks. At the same time, they have a major impact on the company's financial status and production operations. Among them, mobile applications are the next step in the informatization of the power industry. One of the key points of construction. As mobile security issues such as malicious software and privacy theft become increasingly prominent, information security is particularly important. The information and communication department of the State Grid Corporation of China has always been very concerned about the data transmission security of mobile applications, and has issued relevant docu...

Problems solved by technology

Since the one-way authentication does not verify the legitimacy of the RFID terminal, the RFID terminal is easy to be counterfeited, and key production data such as the equipment account are stolen after accessing the main station, which may cause unimaginable consequences.

[0005] The existence of the above problems is mainly due to the fact that there is no reliable technical means to support the legality of identity and data confidentiality of both communication parties. The security of power asset information is facing many difficulties and challenges. In order to properly solve these problems, a two-way authentication method is proposed. Security certification mechanism, this new technical means has become an inevitable choice for the innovation and development of asset security management in power companies
