Method for realizing encryption communication

Abstract

The invention relates to a method for realizing encrypted communication, wherein when two communication nodes communicate, the first node sends itself media ability information and the communication encrypt ability information to the second node; the media ability information represents said node has media ability and the communication encrypt ability represents the node has encrypted communication ability; the second node based on the media ability and communication encrypt ability information, judges if it has the communication encrypt ability and the media ability crossed with the first communication node; if it has, the first and second nodes confirm the same data encrypted key, and use said media ability and the data encrypted key to process encrypted communication. The invention can avoid the communication information between the first and second communication nodes to be obtained illegally, and the illegal user can not analyze or read the content of obtained message, to improve the communication safety.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing encrypted communication. Background technique [0002] Currently, the RFC 2833 protocol describes how to transmit dual-tone multi-frequency signals (DTMF) and other network signaling and events in real-time transport protocol (RTP) packets. [0003] Among the above-mentioned information transmitted by applying RFC 2833, a considerable part of the information requires high security. Such as: transaction data of commercial departments such as banks, user personal information, etc. Encryption should be carried out when transmitting these information with high security requirements, so that the transmitted information cannot be correctly analyzed even if it is obtained illegally. [0004] However, at present, RFC 2833 is used to transmit information without encrypting the transmitted information, and the security of communication using RFC 2833 is low. In this case...

Problems solved by technology

Encryption should be performed when transmitting these information that requires high security, so that the transmitted information cannot be correctly analyzed even if it is obtained illegally

[0004] However, the current application of RFC 2833 does not encrypt the transmitted information when transmitting information, and the security of communication using RFC 2833 is low

In this case, if the information is illegally obtained during transmission, the person who obtains the information illegally can directly read the content contained in the obtained information, which is likely to adversely affect the legal owner of the information, thereby reducing user satisfaction

[0005] In fact, there are still many other types of communication protocols that cannot realize encrypted communication of information, and the security of communication using these communication protocols is also very low, which is likely to have an adverse effect on the legal owner of information, thereby reducing user satisfaction
