Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, it is a schematic diagram of an embodiment of a data transmission method provided by the present invention. In this embodiment, the method includes the steps of:

[0049] Step S1, the verification server receives the transmission instruction sent by the first local server, generates verification information A1, public key PK and private key SK according to the transmission instruction, and sends the verification information A1 and the private key SK back to The first local server sends the public key PK to a second local server;

[0050]In a specific embodiment, after the verification server receives the transmission instruction sent by the first local server, it judges whether the current public key PK and the private key SK ar...

Abstract

The invention provides a data transmission method and system. The method comprises the steps that a verification server outputs verification information A1, a public key and a private key according toa transmission instruction, transmits the verification information A1 and the private key to a first local server, and transmits the public key to a second local server; the first local server encrypts the verification information A1 to form a ciphertext and sends the ciphertext to the second local server through the network server; the second local server decrypts the ciphertext to obtain verification information A2, and sends the verification information A2 to the verification server; the verification server judges whether the verification information A1 and the verification information A2are the same or not, and sends a verification result to the first local server; and it is determined whether the first local server transmits data to the second local server or not according to the verification result. The invention further provides a secure data transmission system. A safety transmission method of the real-time data is established, so that protection measures are provided for anelectric power information system, and the safety of data communication is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and system. Background technique [0002] At the current stage, when the power system transmits information, it mainly uses plain text. The practical application of this method has caused certain hidden dangers in the data security of the power information system. At the same time, due to the low security and confidentiality of the data transmission in the power information system, criminals can steal and tamper with the information, which affects the smooth operation of the power information system. In addition, the data that needs to be transmitted in the power information system is relatively complex and the amount of information is huge. In order to improve the security of real-time data communication in the power system, a safe transmission scheme for real-time data should be established in combination with the protection measures o...
