Problems solved by technology

[0013] (1) In the prior art, when performing data communication, there is usually only one communication channel, that is, as a channel for establishing communication, and as a channel for specific data communication after establishing communication, which is a single-channel communication mode, but If you use a single-channel communication mode to communicate in different domains, the communication channel will be occupied for a long time, which will inevitably lead to congestion of the communication channel, which is not conducive to establishing a large number of communication connections
[0014] (2) In the prior art, the encryption and decryption of communication usually adopt the form of public key encryption and decryption, that is, the form of symmetric key, but this kind of key authentication is easy to cause the password to be leaked, making communication insecure the behavior of
[0015] (3) In the prior art, even if there is a form of using a dynamic key, the dynamic key can be used for a certain period of time, so if it is obtained by other devices, it may still lead to an unsafe situation
But so far, there is no effective way to solve the above technical problems in the prior art

specific Embodiment 1

[0051] see figure 1 , the present invention provides a technical solution: a multi-level cross-domain symmetric key management system based on SIP architecture, including multiple user terminals 1 in different domains, device terminals 2, multiple SIP proxy servers 3, SIP redirection server 4; wherein: at least one SIP proxy server 3 is provided in different domains, and each domain is provided with at least one client 1 and / or device 2; the SIP redirection server 4 is simultaneously in all domains; all The user terminal 1, the device terminal 2, the SIP proxy server 3 and the SIP redirection server 4 are provided with a common public key encryption and decryption key;

[0052] The SIP redirection server 4 is connected with all SIP proxy servers 3 for data communication, and the SIP proxy servers 3 distributed in each domain are connected with the user terminal 1 and the device terminal 2 located in the domain for data communication;

[0053] The user terminal 1 includes a us...

specific Embodiment 2

[0065] On the other hand, the present application also provides a multi-level cross-domain symmetric key management method based on SIP architecture, including a multi-level cross-domain symmetric key management system based on SIP architecture, and the specific key management method is as follows;

[0066] Step S1, when one client A1 sends out a session request with another client B1 or device 2, the user communication socket 6 of client A1 encrypts and decrypts the session request through the client encryption and decryption module 7 using public The key encryption key is encrypted, and the encrypted session request is sent to the described SIP proxy server 3 located in the same domain;

[0067] Step S2, after receiving the session request, the SIP proxy server 3 sends the session request to the SIP redirection server 4;

[0068] Step S3, the SIP redirection server 4 decrypts the encrypted session request by using the public key decryption key, so that the session request in...

Abstract

The invention discloses a multi-level cross-domain symmetric key management system based on SIP architecture, which includes multiple client terminals (1), equipment terminals (2), multiple SIP proxy servers (3), SIP heavy-duty Orientation server (4); Wherein: possess at least one SIP proxy server (3) in different domains, each domain possesses at least one user end (1) and / or equipment end (2); said SIP redirection server (4) be in all domains simultaneously; All described client end (1), described device end (2), described SIP proxy server (3) and described SIP redirection server (4) are provided with common public key encryption and decryption keys. The application of the present invention adopts the mode of communication channel and data communication channel, and establishes a dual channel mode of communication link and data communication, so that the establishment of communication channel and the channel for specific data communication are distinguished, and the two do not affect each other, thereby speeding up data communication. communication, increasing data security.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a multi-level cross-domain symmetric key management system and a management method based on SIP architecture. Background technique [0002] Network communication includes a variety of secure communication protocols. SIP (Session Initiation Protocol) is an application layer signaling control protocol. A session for creating, modifying, and releasing one or more participants. These sessions can be Internet multimedia conferences, IP telephony or multimedia distribution. Participants in a session can communicate via multicast, mesh unicast, or a combination of the two. With SIP, service providers can choose standard components at will. Users can find and connect with each other regardless of the media content and the number of parties involved. SIP negotiates sessions so that all parties can agree on and modify the functionality of the session. It can even add, delet...
