<p>The aim of the invention is to optimise the creation of a secure application domain between a computer system and an electronic entity. After having generated (305) and transmitted (310) a code to the computer system, said computer system calculates (320) a signature from the received code and transmits (325) same, along with a certificate, to the electronic entity, the certificate and the signature allowing the authentication of the computer system. The electronic entity then checks (330) the validity of the received certificate and signature, the signature being checked according to the generated code, in order to authenticate the computer system. In response to the authentication of the computer system, at least one cryptographic key allowing the creation of said secure application domain is generated (330).</p> |
