Patent ID: 7715565

Claim:
A system for encrypting a data encryption key, the system comprising: a key encryption key generator configured to receive a public key portion of a label, the label including an asymmetric key pair including of the public key portion and a private key portion, the key encryption key generator being further configured to process the public key portion of the label to obtain a key encryption key; a data encryption key encoder configured to receive the key encryption key from the key encryption key generator and to receive a data encryption key from a random number generator, the encoder being further configured to encrypt the data encryption key using the key encryption key to produce an encrypted data encryption key and to provide the encrypted data encryption key to an encryption device for forwarding with data encrypted using the data encryption key; and a combiner configured to receive and to combine at least two pieces of the label to provide the public key portion of the label to the key encryption key generator, wherein the at least two pieces of the label are the result of a parsing process applied to the label that produces pieces of the label, wherein each piece of the label is useless for indicating a key unless combined with at least one other piece of the label.
