Example Embodiment

[0056] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art fall within the protection scope of the present invention.

[0057] According to an embodiment of the present invention, a method for initiating communication information is provided.

[0058] Such as figure 1 As shown, the method for initiating communication information according to the embodiment of the present invention includes:

[0059] Step S101, before the communication data is sent, the communication initiator generates a first key, and uses the second key to initially encrypt the first key;

[0060] Step S103, after t...

Abstract

The invention discloses a method and device for sending and receiving communication information and a safety protection system. The method for sending the communication information includes the steps that a communication sending party generates a first secret key before communication data are sent, initial encryption is conducted on the first secret key through a second secret key, the communication sending party conducts secondary encryption on the initially-encrypted first secret key through a third secret key after initial encryption is conducted, the communication sending party sends the secondarily-encrypted first secret key to a communication receiving party, and the communication sending party is in encryption communication with the communication receiving party through the first secret key. Encryption is conducted on the communication data before the communication data are sent, secondary encryption is conducted on the encrypted communication data when the communication data are sent, and therefore dual-level protection is achieved for the communication data, communication software is prevented from monitoring the communication data of a user, and privacy is prevented from being revealed.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method for initiating and receiving communication information, an initiating and receiving device, and a security protection system. Background technique [0002] In recent years, with the development of the Internet, instant messaging software has become an indispensable means of communication for people. People use instant messaging software for communication almost every day. Instant messaging software has brought great convenience to people's lives. [0003] At present, in order to protect the user's communication data from being leaked, the existing instant messaging software will use its own data transmission encryption method to encrypt the user's communication data when the user communicates through the instant messaging software. certain protection. However, this kind of guarantee is a temporary solution, not the root cause, and it cannot fundamentally guarantee the se...
