Example Embodiment

[0102] Embodiment 1, information communication between two client terminals in the wide area network

[0103] Considering that the quantum network service station where the client A and client B are located is very stressed in the prior art, this embodiment uses a method of directly connecting the client A and client B to reduce the pressure on the quantum network service station. In this embodiment, it is assumed that the KA and KP of the quantum key card matched by client A are recharged at quantum network service station A, the KB of the quantum key card matched by client B is recharged at quantum network service station B, and KP is Recharge at Quantum Network Service Station A.

[0104] In order to realize the direct communication between client A and client B, the following three methods can be adopted respectively:

[0105] Method 1: The quantum network service station distributes session keys to client A and client B.

[0106] 1. Client A sends a session key request ...

Example Embodiment

[0216] Embodiment 2, two client terminals belonging to a quantum network service station communicate in the local area network

[0217] When both client A and client B belong to the same quantum network service station, there is no need to use quantum key distribution equipment to generate new inter-station quantum keys, and only need to use the user-side key stored by the quantum network service station Encrypt and decrypt the transmitted ciphertext information.

[0218] Client A and Client B respectively use their matching quantum key cards to complete the identity authentication with the quantum network service station.

[0219] In order to reduce the pressure on the quantum service station, three methods can be used to realize the direct communication between client A and client B respectively.

[0220] Method 1: The quantum network service station distributes session keys to client A and client B.

[0221] 1. Client A sends a session key request to the sub-network servi...

Abstract

The invention discloses an information encrypted/decrypted transmission communication system and method based on group type quantum secret key cards. The communication system comprises a quantum network service station configured in the network side and two clients configured in the user side, each client is provided with the quantum secret key card, each quantum secret key card stores a public key and a private key, all the quantum secret key cards and one quantum network service station share the public key, each quantum secret key card and one corresponding quantum network service station share secret key; when the two clients make communication, the clients obtains a session secret key directly or indirectly via the quantum network service station by using the public and private keys in the matched quantum secret key cards; and then, the clients encrypt and decrypt information via the session secret key in the corresponding quantum secret key card for transmission. The burden in the network side is reduced, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of quantum communication, in particular to a secure communication system and communication method for realizing encryption, decryption and transmission of information transmitted between members based on a quantum network. Background technique [0002] With the outbreak of the information revolution in the 21st century and the continuous development of science and technology, how to ensure the secure communication between users is the current research focus. Realizing information security such as data encryption, transmission and privacy, whether it is a company that conducts daily business activities, or government agencies, banks, etc. have urgent needs for this, especially in today's globalized economy era, to ensure the unconditional security of information , is one of the focuses of the current public attention. It was first proposed that the transmission of communication information between users is a...
