Patent ID: 8554680

Claim:
A method in a computer system for providing access to previously downloaded secure data comprising: registering a subscriber at the computer system by receiving a public key portion of a first asymmetric encryption key pair; establishing a session at the computer system with the registered subscriber, including generating a first symmetric session key; exchanging encrypted subscription data with a client computer system from the computer system using a combination of the first symmetric session key and the public key portion of the first asymmetric encryption key pair; re-registering the subscriber at the computer system; establishing a second session at the computer system with the re-registered subscriber, including generating a second symmetric session key; and enabling decryption of the previously exchanged encrypted subscription data without causing the previously exchanged encrypted subscription data to be re-downloaded by forwarding a list of previously used one-time session keys to the client computer system, wherein the list includes at least the first symmetric session key, and wherein the list is encrypted using a public key portion of a second asymmetric encryption key pair.
