Abstract
A sending device generates a first and a second KMM, wherein the first KMM includes a first KEK and a KMM encryption key, and the second KMM includes a set of symmetric encryption keys. The sending device further encrypts the set of symmetric encryption keys using the first KEK; encrypts the first KEK and the KMM encryption key using a first public key of a receiving device; and encrypts the second KMM using the KMM encryption key to generate an encrypted second KMM before sending the first KMM and the encrypted second KMM to the receiving device. The receiving device decrypts the first KEK and the KMM encryption key using a first private key that corresponds to the first public key; and decrypts the encrypted second KMM using the KMM encryption key to obtain the encrypted set of symmetric keys.
