A first encrypted master key Km is received at the receiver device from a transmitter device, the first encrypted master key Km secured by a receiver public key Kpub-rx. The first encrypted master key Km may be decrypted with a receiver private key Kpri-rx to obtain the master key Km. The master key Km may be encrypted using a block cipher that applies a receiver secret key Kh to obtain a second encrypted master key.
