Abstract
A system and method for storing encrypted electronic data using a transmission Control Protocol (TCP), requires leaving both the header and the first 48 bytes of the “0” data packet in the data area of the TCP format in clear text. Consequently, the data can be routed to a main address (storage facility), and then to a sub-address (storage device) for storage. A single compression/encryption operation can be accomplished, before storage, at the host (server), the network switch, or the final storage device.
Claims20
A method for transferring encrypted electronic data from a host server, via a main address of a storage facility, to a final sub-address of a storage device, the method comprising the steps of:
- identifying a header portion and a data area for the electronic data being transferred, wherein the header portion includes the main address of the storage facility;
- dividing the data area into a first part and a second part, wherein the sub-address of the storage device is in the first part;
- encrypting the second part of the data area;
- and
- transferring the electronic data, via the main address, to the sub-address of the storage device.
A method for transferring electronic data to a storage device, wherein the electronic data is formatted in accordance with a Transmission Control Protocol (TCP) and has a header and a data area, the method comprising the steps of:
- encrypting a selected portion of the data area;
- transferring the electronic data to a main address of a storage facility;
- and
- routing the electronic data from the main address of the storage facility to a sub-address of the storage device for storage.
A system for transferring electronic data to a storage device, wherein the electronic data is formatted in accordance with a Transmission Control Protocol (TCP) and has a header and a data area, the system comprising:
- a means for encrypting a selected portion of the data area;
- a means for transferring the electronic data to a main address of a storage facility;
- and
- a means for routing the electronic data from the main address of the storage facility to a sub-address of the storage device for storage.
