Embodiment 1
[0129] This embodiment provides a method for implementing the SSH protocol based on post-quantum key exchange, which can effectively prevent the shared key generated by the communicating client and server from being breached by a quantum computer; trusted status.
[0130] The protocol structure of the SSH improvement scheme is the three-layer system architecture stipulated by the current SSH protocol. For the specific protocol architecture, refer to figure 1 . From bottom to top, SSH is the transport layer, user authentication, and connection establishment. The session establishment process includes version negotiation, algorithm negotiation, key negotiation, user authentication, and connection request.
[0131] At present, the process of remote login between the communication parties using the SSH protocol is as follows: figure 2 shown.
[0132] The first step is version negotiation: the client and the server send their protocol version number and software version number ...
Embodiment 2
[0288] This embodiment provides a system for implementing the SSH protocol based on post-quantum key exchange, which can effectively prevent the shared key generated by the communicating client and server from being breached by a quantum computer; on the other hand, it can also verify both the client and the server trusted status.
[0289] The system for implementing the SSH protocol based on post-quantum key exchange includes a key exchange module, and the key exchange module includes a first key unit, a second key unit, a first verification unit, and a second verification unit, wherein:
[0290] The first key unit is located in the server and is used to complete the following functions:
[0291] Randomly sample from the Gaussian distribution of the first parameter, and calculate the public-private key pair of the server;
[0292] After the first verification unit passes the identity authentication of the client, it calculates the temporary session public key of the server f...
