Abstract
An encryption system permits end-to-end encryption of information over an untrusted interconnection network. The information encryption system includes at least one client for processing information. The system also includes at least one storage device for holding the information. At least one key server provides a data key for encrypting and decrypting the information. An encryption module is associated with each client. Each encryption module has a first processor accessing a first memory and a second processor accessing a second memory different from the first memory. The first processor communicates with the associated client. The second processor communicates with the storage device. The first processor communicates with the second processor through a dedicated channel. The second processor obtains the data key from the key server. Information is received from the first processor over the dedicated channel and encrypted using the data key. The encrypted information is then stored on the storage device. The second processor also reads the encrypted information from the storage device, decrypts the information using the data key, and sends the decrypted information to the first …
