Patent 9185088 was granted and assigned to Amazon on November, 2015 by the United States Patent and Trademark Office.
Techniques are disclosed for secure and efficient communication from a source to a destination through an intermediary. The disclosed techniques employ a source-to-intermediary encryption algorithm to encrypt the communication from the source to the intermediary. The disclosed techniques also employ an intermediary-to-destination encryption algorithm to encrypt the communication from the intermediary to the destination. Thus, a more optimal encryption algorithm may be employed for communication between the intermediary and the destination, even if the more optimal encryption algorithm is not supported by the source. Also, a more optimal encryption algorithm may be employed for communication between the source and the intermediary, even if the more optimal encryption algorithm is not supported by the destination.
