Abstract
Transmitter, receiver, system and method for secure data communications are provided. The transmitter encodes data as a spatial symbol in accordance with a codebook to transmit spatially encoded data through the optical channel. The receiver detects a spatial symbol from spatially encoded data received through the optical channel, and generates a data value based on a codebook and the spatial symbol.
Claims25
A transmitter for secure data transmission over an optical channel, comprising:
- a mask for transmitting a spatial symbol into the optical channel;
- and
- a controller configured to:
- encode incoming data as a spatial symbol in accordance with a first codebook, and
- control the mask based on the spatial symbol to transmit the spatial symbol through the optical channel.
The method of 6 wherein the transmitter is further configured to notify at least one of the receiver and the controller of a change of the codebook.
A method for secure data transmission over an optical channel, comprising:
- encoding incoming data as a spatial symbol in accordance with a codebook;
- and
- transmitting the spatial symbol through the optical channel.
A receiver for secure data communication over an optical channel, comprising:
- a mask for generating a signal based on detection of a spatially encoded symbol received over the optical channel;
- and
- a controller configured to:
- identify the received symbol in accordance with the generated signal;
- decode the spatial symbol into a data value in accordance with a codebook.
A method for decoding spatially encoded data received over an optical channel, comprising:
- generating a signal based on spatially encoded data received over the optical channel;
- identifying a spatial symbol from the signal;
- and
- decoding the spatial symbol into a data value in accordance with a codebook.
