Problems solved by technology

[0002] At present, smart terminal devices such as smartphones are widely popularized. When users use these smart terminal devices to communicate, the communication content is easily monitored and stolen by malicious software.
However, the existing encrypted communication methods usually use software encryption algorithm or hardware encryption algorithm, and the key information is generated by one party and sent directly to the other party. The call process is maliciously attacked, bringing security risks to users

Embodiment 1

[0036] see figure 1 , figure 1 It is a schematic flowchart of a key management method provided in Embodiment 1 of the present invention. The execution subject of this embodiment includes a local device, a peer device terminal, and a server, wherein both the local device and the peer device are terminals The device, specifically, may be a device such as a smart phone or other smart terminals. figure 1 The illustrated method of key management may include the following steps:

[0037] S101. If the local device detects that the user triggers the operation of communicating with the peer device, it sends a key application message to the key management server, wherein the key application message carries the local device identifier, and the key application message is used to apply for session key.

[0038] Specifically, the key management server is mainly used to complete key generation, encrypted storage, encryption and decryption process, and key management.

Abstract

The embodiment of the invention discloses a key management method and system. The key management method includes the steps: if home terminal equipment detects that a user triggers the operation on opposite terminal equipment, the home terminal equipment sends a key application message to a key management server; according to the received key application message, the key management server generates a session key corresponding to an identifier of the home terminal equipment randomly, and sends the session key to the home terminal equipment; if the home terminal equipment receives the session key, the home terminal equipment sends a communication request to the opposite terminal equipment; according to the identifier of the home terminal equipment included in the communication request, the opposite terminal equipment requests the key management server to acquire the session key corresponding to the home terminal equipment; and if the opposite terminal equipment receives the session key, the opposite terminal equipment gives a response to the communication request and establishes communication connection with the home terminal equipment. The technical scheme of the key management method and system enables both the home terminal equipment and the opposite terminal equipment to safely acquire the session key of the communication of this time, thus improving generation safety and transmission safety for the session key, and guaranteeing safe transmission of the communication content.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a key management method and system. Background technique [0002] At present, smart terminal devices such as smart phones are widely popularized. When users use these smart terminal devices to communicate, the communication content is easily monitored and stolen by malicious software. However, the existing encrypted communication methods usually use software encryption algorithm or hardware encryption algorithm, and the key information is generated by one party and sent directly to the other party. The call process is maliciously attacked, which brings security risks to users. Contents of the invention [0003] Embodiments of the present invention provide a key management method and system, which can improve key generation security and transmission security of encrypted communication, thereby ensuring secure transmission of communication content.
