The present invention relates to a communication method, implementing a mobile device (10), a contactless card (11), and a remote server (12), for securely and remotely downloading access keys to said contactless card (11) using said mobile device (10). The method according to the present invention uses asymmetric cryptography methods, the data being encrypted with a public encryption key of said contactless card (11), and said public encryption key being exported by said remote server (12), a mutual authentication being carried out between said contactless card (11) and the remote server (12). A data structure (24) constructed by the remote server (12) includes, before transmission, the encryption of said data structure (24) using the public key of the certificate of the EAP-TLS stack installed on the RFID chip (21) and a signature. |
