Abstract:
In response to at least one message received by a processor of a gateway server from a user device wherein each message requests that an encryption key be downloaded to the user device, the processor generates at least one unique encryption key for each message and sends the at least one generated encryption key to the user device, but does not store any of the generated encryption keys in the cloud. For each encryption key having been sent to the user device, the processor receives each encryption key returned from the user device. For each encryption key received from the user device, the processor stores each received encryption key in the cloud.

Claim (Index 14):
The computer program product of  claim 9 , wherein said receiving each encryption key returned from the user device comprises receiving a second encryption key returned from the user device, wherein said storing comprises storing the second encryption key in the cloud at a second key storage time after the first data storage time, wherein the encrypted first data is denoted as singly encrypted first data, and wherein the method further comprises:\n said processor encrypting the singly encrypted first data, at another first data encryption time after the second key storage time, by using the second encryption key to encrypt the singly encrypted first data to form a doubly encrypted first data; and said processor decrypting the doubly encrypted first data, by using the second encryption key to decrypt the doubly encrypted first data to form the singly encrypted first data, followed by using the first encryption key to decrypt the singly encrypted first data to form the first data unencrypted.
