摘要：The present invention relates to a security management system (SYS) forsecuring a communication between a remote server (SP) and an electronic device (D),wherein said electronic device (D) being operated to: - generate a first value by encodinga master key (t1) with a generated mask (m); - encode the mask (m) with a cryptographickey retrievable by the remote server; - compute a signature (s), - compute a first sessionkeys (kEnc1, KMac1) based on a key derivation function of said master key (t1); saidremote server (SP) being operated to: - receive said encrypted mask (Enc) and saidsignature (s) transmitted by the electronic device; - authenticate said electronic device (D)based on a verification and a validation of the signature (s); - decrypt said encoded maskwith a retrieve cryptographic key; using said decrypted mask to decrypt the encodedmaster key, - compute a second session keys (Kenc2, Kmac2) based on said decryptedmaster key; - encode a message (M1) with the second session keys (Kenc2, Kmac2); - uponreception of the encoded message, the electronic device being operated to authenticate
the remote server based on a successful decryption of the encoded message with thefirst session keys, a secure message channel is established between the electronic deviceand the remote server when the authentication of the remote server is successful.
