System for providing physical layer security

A system comprising:

• a transmitter device including a transmitter physical layer security module;
• and
• a receiver device including a receiver physical layer security module,
• the transmitter device being operable to:
• generate a transmitter security configuration;
• transmit the transmitter security configuration to the receiver device;
• configure the transmitter physical layer security module in accordance with the transmitter security configuration;
• process user data with the transmitter physical layer security module to produce secured data;
• and
• transmit the secured data to the receiver device,
• the receiver device being operable to:
• receive the transmitter security configuration from the transmitter device;
• generate receiver configuration data from the received transmitter security configuration;
• configure a receiver physical layer security module in accordance with the receiver configuration data;
• and
• process data received from the transmitter device with the receiver physical layer security module to recover the user data,
• wherein the transmitter security configuration specifies a configuration of the transmitter physical layer security module such that decoding the secured data as received by an eavesdropper results in a bit error rate of about one-half.

A system comprising:

• a physical layer security transmitter device including a display;
• and
• a physical layer security receiver device including a user input device,
• the transmitter device being operable to:
• generate a transaction identifier;
• generate transmitter security configuration from the transaction identifier;
• present the transaction identifier on the display;
• configure a transmitter physical layer security module in accordance with the transmitter security configuration;
• process user data with the transmitter physical layer security module to produce secured data;
• and
• transmit the transformed data to the receiver device,
• the receiver device being operable to:
• obtain, through the user input device, the transaction identifier;
• generate inverse transformer configuration data from the obtained transaction identifier;
• configure a receiver physical layer security module in accordance with the transmitter security configuration;
• and
• process data received from the transmitter device with the receiver physical layer security module to recover the user data,
• wherein the transmitter security configuration specifies a configuration of the transmitter physical layer security module such that decoding the transformed data as received by an eavesdropper results in a bit error rate of about one-half.

A method of securing user data during transmission, the method comprising:

• generating, by a transmitter device, a transaction identifier;
• generating, by the transmitter device, a transmitter security configuration from the transaction identifier;
• securely transmitting, by the transmitter device to a receiver device, the transaction identifier or the transmitter security configuration;
• configuring, by the transmitter device, a physical layer security module in accordance with the transmitter security configuration;
• processing, by the transmitter device, user data with the configured transmitter physical layer security module to produce secured data;
• and
• transmitting, by the transmitter device to the receiver device, the secured data,
• wherein the transmitter security configuration specifies a configuration of the transmitter physical layer security module such that decoding the secured data as intercepted by an eavesdropper results in a bit error rate of about one-half.
