Each device is associated with an asymmetric cryptography pair, each pair including a first private key and a first public key. Respective second private and public keys may be determined based on the first private key, first public key and a deterministic key. A secret may be determined based on the second private and public keys. The data at the electronic device (3) may be encrypted using the --25 determined secret or an encryption key that is based on the 23 zs secret. Information indicative of the deterministic key may be sent to the key device (5) where the information may be stored. 14 13 11 15 W O 20 17 / 145 00 2 Al Eavesdropper Fig. 1
