Abstract
The present invention provides a method for establishing a secure communication channel between a client (C) and a remote server (S), said client (C) and remote server (S) exchanging data through an intermediate entity (G), said client (C) having a long-term key pair (sk,pk), said remote server generating an ephemeral key (sk,pk), the method comprising a mutual authentication step wherein the client (C) sends a public key (pk) of said long-term key pair (sk, pk) and the proof that said public key (pk) is valid to the server (S), and wherein the remote server (S) sends the public key (pk) of said ephemeral key pair (sk,pk) to the client (C). The client (C) generates an ephemeral key pair (skC,pkC) and sends the public key (pK) of said ephemeral key pair (sk,pk) to the server (S) so as to generate a secret common to the client (C) and to the remote server (S) for opening the secure communication channel.
