Abstract

The invention provides an encrypted communication method and device based on the SM9 algorithm. The method includes: the first user equipment uses the identification information of the second user equipment as the SM9 public key, and uses the SM9 algorithm to encrypt the first encryption key to obtain an encrypted first encryption key; the first encryption key is an encryption key of a preset first encryption algorithm; the first user equipment uses the first encryption algorithm to encrypt information to be sent according to the encrypted first encryption key to obtain encrypted information; the The first user equipment sends the encrypted information and the encrypted first encryption key to the second user equipment. The embodiment of the present invention realizes the safe communication between multiple user equipments and the function of safe group sending of messages.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an encrypted communication method and device based on the SM9 algorithm. Background technique [0002] With the continuous progress of global information technology, the level of social information application in our country has also developed by leaps and bounds. Electronic products emerge in endlessly, which greatly facilitate people's work and life. However, with the substantial increase in the penetration rate of electronic products, its security and confidentiality issues have become increasingly prominent. When users communicate through electronic products, the communication is easily intercepted and obtained by illegal elements. [0003] Nowadays, digital certificates are generally used to achieve security and confidentiality, that is, to use the key of the certification authority to protect data. A digital certificate is a file that is digitally signed by ...
