Problems solved by technology

[0003] Traditional security gateways use the normal transmission application mode. In the process of processing inbound packets, the traditional packet processing scheme is to convert the received encrypted data packets through conventional decryption to obtain the original IP data. However, The security of the traditional transmission method is not high, especially in the processing of inbound messages. The conventional encryption and decryption methods are easy to be cracked after a long time of use, making the data easy to be intercepted during transmission. After decrypting the encapsulated data, you can get Raw data, leading to leakage of confidential information, resulting in immeasurable losses

Abstract

The invention discloses an inbound message processing method based on a power gateway, comprising: receiving an encrypted data message transmitted by a sending end and searching for an SA protocol associated with the encrypted data message according to a local policy; the SA protocol Including an encryption algorithm and an algorithm key; decapsulating the encrypted data message to obtain encrypted data and an authentication message; calculating the original data message through a verification algorithm to obtain verification data; When the verification data is consistent with the authentication message, the encrypted data is decrypted by the algorithm key in the SA protocol to obtain the original data; after the original data is obtained, the counter is invoked, and the counter is The value of the counter increases the preset constant value, and when the value of the counter reaches the preset maximum value, a new SA protocol is generated through protocol communication with the receiving end; the technical solution of the present invention can improve the security in the data transmission process and avoid confidential information Leaked.

Description

technical field [0001] The invention relates to the field of gateway inbound message processing, in particular to a power gateway-based inbound message processing method and device. Background technique [0002] The security gateway is widely used in the power distribution industry. By deploying the security gateway at the network boundary, it can ensure the security, confidentiality and integrity of cross-network information transmission, and realize effective authentication, authorization and data transmission security between the client and the server; Therefore, the access method of the security gateway is an important link in the gateway technology. [0003] Traditional security gateways use the normal transmission application mode. In the process of processing inbound packets, the traditional packet processing scheme is to convert the received encrypted data packets through conventional decryption to obtain the original IP data. However, The security of the traditiona...
