Abstract
Methods and systems for encrypting and decrypting data are described. An exemplary system includes an optical transceiver that includes at least one of an encryption block and a decryption block. The optical transceiver also has at least one encryption and decryption key stored at the transceiver. The encryption block receives unencrypted data and performs encryption operations on the data using the encryption and decryption key. The decryption block receives encrypted data and performs a decryption operation using the encryption and decryption key.
Claims20
A transceiver comprising:
- a transmitter optical subassembly;
- a receiver optical subassembly;
- at least one encryption and decryption key;
- and
- at least one of:
- an encryption block operably connected to the transmitter optical subassembly, wherein the encryption block is configured to perform an encryption operation on data received from a host device using the at least one encryption and decryption key and to provide the resulting encrypted data to the transmitter optical assembly;
- and
- a decryption block operably connected to the receiver optical subassembly, wherein the decryption block is configured to perform a decryption operation on data received from the receiver optical subassembly using the at least one encryption and decryption key.
In an optical transceiver that includes at least one of an encryption block and a decryption block and further includes at least one encryption and decryption key, a method for encrypting and/or decrypting data at the optical transceiver, the method comprising:
- an act of receiving unencrypted data at an encryption block from a host device that is coupled to the optical transceiver;
- an act of the encryption module performing an encryption operation on the received unencrypted data using the at least one encryption and decryption key to thereby encrypt the data;
- and
- an act of transmitting the encrypted data to a remote optical transceiver.
