Key service-oriented architecture based on multi-terminal communication and distribution method

Abstract

The invention relates to key service-oriented architecture based on multi-terminal communication and a distribution method. The key service-oriented architecture comprises a key service system, a plurality of personal key storage spaces are formed in the key service system; each client can access the corresponding personal key storage space, and cannot access the personal key storage space of other clients; the key service system is further provided with a client online management server, wherein the client online management server is used for monitoring whether each client is in the online connection state, and pushing a session key to each client in online state. Compared with the prior art, the aim of security communication in multi-party clients can be realized by only adopting the data packet session key encryption way, and the one-packet key high-standard requirement to the QKD system is avoided at the same time, the quantum encryption communication can be well suitable for the large-scale multi-party communication occasion; the key service-oriented architecture guarantees that the participants can rapidly and accurately receive the session keys, and the security and the efficiency of the communication are improved.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to a multi-terminal communication-based key service architecture and distribution method. Background technique [0002] With the widespread popularization of the Internet, information transmission among human beings has reached an unprecedented quantity and frequency, and various private information is increasingly exposed on the Internet. Therefore, human beings' demand for confidential communication has also reached an unprecedented height. The current Internet information security encryption method is called "public key" cryptography system. Its principle is to generate a public key that spreads on the network and a private key that stays inside the computer through an encryption algorithm. The two keys must match Use to achieve a complete encryption and decryption process. [0003] The encryption standard used by the modern Internet is the RSA algorithm born in the...
