Abstract

This invention published a method of encrypted communication. The method comprises: a receiving terminal receives a secret key and data from a sending terminal, wherein the secret key is one that is established by the sending terminal based on ID information obtained by negotiation with the receiving terminal and the data are ones obtained by secret-key encryption by the sending terminal; the receiving terminal stores the secret key into a safety region and stores the data into a common region; and the receiving terminal decrypts the data based on the secret key. In addition, the invention also discloses a sending terminal apparatus and a receiving terminal apparatus for encrypted communication, and a system of encrypted communication. Therefore, only one pair of secret keys is set between one pair of terminals and only the two sides in communication are able to decrypt the communication data, so that differential encryption in communication is realized; only the two sides in communication are able to parse the secret key, so that no server needs to be erected; and during data decryption, only local data need to be read. The communication safety is high and the processing efficiency is improved.

Description

technical field

[0001] The invention relates to communication technology, in particular to an encrypted communication method, device and system. Background technique

[0002] In modern society, communication technology has penetrated into every aspect of people's life and has become a very important part of people's daily life. In order to ensure the information security of both communication parties, the communication information needs to be encrypted.

[0003] The current encryption communication method mainly has the following problems: the chat between the communication parties cannot be differentially encrypted, and it can be easily parsed when copied to all similar communication devices or communication protocols, and the security is poor. Contents of the invention

[0004] In order to solve the above technical problems, the present invention provides an encryption communication method, device, and system, which can realize differentiated encryption of data transmis...
