Embodiment Construction

[0068]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0069] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a message parsing system provided by the present invention. The system includes a source device and a destination device, multiple network devices, and a control device. The transmission of a message from a source device to a destination device needs to be forwarded by multiple network devices. In the actual scenario of the embodiment of the present invention, message f...

Abstract

The application discloses a message analysis method and equipment, which help to ensure the reliability of the source and the integrity of the analysis results, and improve security. The method includes: the source device receives the first ciphertext sent by the control device, the first ciphertext is used to verify the reliability of the message from the parsing device, and the parsing device is the path between the source device and the destination device selected trusted device; the source device obtains a second message including the first ciphertext according to the first ciphertext and the first message; the source device sends the second message. The parsing device may obtain a third message including verification information and the first ciphertext according to the second message and the device identifier of the parsing device. The destination device may receive the third message sent by the parsing device, and use the verification information included in the third message and the first ciphertext to verify the third message from the parsing device. reliability.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message analysis method and equipment. Background technique [0002] In a scenario where multiple namespaces coexist, different namespaces can be used to describe entities in the network, such as network addresses of network objects, IDs (identifiers) of users in applications, and so on. In a system where multiple namespaces coexist, it is necessary to parse packets carrying name information transmitted between different network devices, and devices that complete cross-namespace parsing, such as routers and gateways, are vulnerable to hacker attacks. For example, modify the domain segment in the packet in the IP network to bypass the filtering of the firewall, or modify the destination IP address to forward the packet to the wrong address. [0003] At present, DNS (domain name system, domain name system) can be used as a resolution device, and communication secu...
