Safe data transmission method based on Real-Time Messaging Protocol (RTMP) connections

Abstract

The invention discloses a safe data transmission method based on Real-Time Messaging Protocol (RTMP) connections. The method has the advantages that functional extensions of the RTMP are carried out, and through a key negotiation process between a client and a server, an encryption algorithm and a key adopted by each connection are random, so that external cracking analysis of encrypted data is much more difficult; the symmetrical encryption algorithms are adopted for encryption processing, so that the encryption and decryption processing efficiencies are high, real-time performance of data transmission and user experience are not obviously affected, and the effects on the processing load of the server are small; meanwhile, the server can flexibly select an encryption mode, and, according to a user type or a resource type requested by a user, can determine whether encrypted transmission is needed or not or select one specific encryption algorithm and a key length (the keys with a length of 64 bytes or more can be provided, and the number of the encryption algorithms can reach 255).

Description

technical field [0001] The invention belongs to the technical field of data security transmission, in particular to an RTMP connection-based data security transmission method. Background technique [0002] With the rapid development of the Internet, people are also facing information security issues while enjoying the convenient services brought by the Internet. The rapid development of teleconferencing, online transactions, online banking and other fields has led to the increasing importance of data security. more and more prominent. Data encrypted transmission is a very important and commonly used technical means in the field of information security. The key data is encrypted by the sender through a certain algorithm, and becomes unrecognizable ciphertext data to reach the destination through the Internet. The decryption method decrypts the ciphertext data and restores it to readable data. Encrypted data transmission can greatly increase the difficulty of data being anal...

Problems solved by technology

Since the RTMP protocol itself does not have a data security protection mechanism, the data is transmitted in plain text on the channel established by the sending and receiving parties. In addition to the openness of the protocol, the data can be easily obtained and analyzed by a third party during the transmission process. Therefore, using the standard RTMP protocol for data transmission has a very high risk in terms of information security. It is difficult to avoid malicious attacks such as data theft and information tampering from the outside. It is not usable in scenarios that require security for data transmission.
