Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0045] A log is a character string formed in a network device according to a certain standard format, and is used to record characteristic information of packets, user operation information, or network access information. Among them, one character occupies one byte.

[0046] Such as figure 1 The log system shown includes a network device 100 and a server 101 . The log system may include multiple network devices, and here only one network device 100 is taken as an example for illus...

Abstract

The embodiment of the present application provides a log encryption and decryption method. The log encryption method includes: the network device obtains the log, and the log includes a time stamp and log content; the network device determines the target key according to the basic key agreed with the server; the network device uses The target key encrypts the log content to obtain the encrypted log content; the network device determines the encrypted log according to the encrypted log content and the time stamp; the network device sends the encrypted log to the server. By applying the embodiment of the present application, the security of the network is effectively improved.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a log encryption and decryption method. Background technique [0002] A log is a character string formed in a network device according to a certain standard format, and is used to record characteristic information of packets, user operation information, or network access information. Through the obtained logs, network administrators can understand the access status of the network and the operation status of network devices. [0003] In order to prevent the log from being stolen, a shared key is used between each network device and the server. The key is a string of strings, and the corresponding log is encrypted using the shared key. Specifically, after the network device generates the log, it encrypts the log according to the shared key, and sends the encrypted log to the server. The server decrypts the log according to the shared key to obtain the original lo...
