Abstract
Embodiments of the present disclosure provide a secure communication method, a client and a non-public server. The secure communication method includes: generating a set of destination addresses of a non-public server based on an IPv6 prefix of the non-public server, and a signature string and a user ID of a client, wherein the signature string is obtained by signing an IPv6 address and the user ID of the client based on a private key of the client; initiating a set of connection request to the non-public server based on a set of communication connections containing the set of destination addresses, for the non-public server to determine a public key corresponding to a user ID based on the user ID in the set of destination addresses, verifying the set of communication connections based on the public key, and establishing communication when the verification of the set of communication connections passes.
