Abstract
A receiver in a communication system may include a buffer and hardware. The buffer may be configured to store a communication signal comprising one or more pulses representative of data. The hardware may be configured to determine whether a data authentication pulse has been superimposed over at least one of the one or more pulses, and authenticate, based on the determination of whether the data authentication pulse has been superimposed over at least one of the one or more pulses, the one or more pulses as a valid representation of the data.
Claims18
A method comprising:
- receiving, by a receiver, a communication signal comprising one or more pulses representative of data;
- determining, by the receiver, whether a data authentication pulse has been superimposed over at least one of the one or more pulses, wherein the data authentication pulse includes a data authentication pulse having a voltage that is at least one order of magnitude less than a voltage of the one or more pulses representative of the data;
- and
- authenticating, by the receiver and based on the determination of whether the data authentication pulse has been superimposed over at least one of the one or more pulses, the one or more pulses as a valid representation of the data.
A receiver in a communication system, the receiver comprising:
- a buffer configured to store a communication signal comprising one or more pulses representative of data;
- and
- hardware configured to:
- determine whether a data authentication pulse has been superimposed over at least one of the one or more pulses, wherein the data authentication pulse includes a data authentication pulse having a voltage that is at least one order of magnitude less than a voltage of the one or more pulses representative of the data;
- and
- authenticate, based on the determination of whether the data authentication pulse has been superimposed over at least one of the one or more pulses, the one or more pulses as a valid representation of the data.
A system comprising:
- a hardware transmitter configured to:
- obtain a communication carrier signal that includes one or more pulses representative of data;
- superimpose, in accordance with a pseudo random sequence, a data authentication pulse on top of at least one of the one or more pulses to obtain an encrypted communication signal, wherein the data authentication pulse includes a data authentication pulse having a voltage that is at least one order of magnitude less than a voltage of the one or more pulses representative of the data;
- and
- transmit the encrypted communication signal;
- and
- a hardware receiver configured to:
- receive the encrypted communication signal;
- determine, according to the pseudo random sequence, whether the data authentication pulse has been superimposed over the at least one of the one or more pulses;
- and
- authenticate, based on the determination of whether the data authentication pulse has been superimposed over the at least one of the one or more pulses, the one or more pulses as a valid representation of the data.
