Abstract
A pairing apparatus according to an exemplary embodiment of the present invention includes: a noise filtering part for filtering a noise on a power line; and a processor for pairing with a pairing target device and performing an authentication by generating a secret key using the filtered noise and by using the generated secret key.
Claims11
A pairing apparatus, comprising:
- a noise filtering part for filtering a noise on a power line;
- and
- a processor for generating a secret key using the filtered noise and for performing a pairing and an authentication with a pairing target device using the generated secret key;
- wherein the processor samples the filtered noise, synchronizes a sampling rate and a sampling time by transmitting the sampling rate to and receiving the sampling rate from the pairing target device, extracts a bit sequence by comparing a maximum absolute value and an average value of each period of the sampled noise, transmits an error correcting code of the extracted bit sequence to and receiving the error correcting code of the extracted bit sequence from the pairing target device, and generates the secret key by reconciling the extracted bit sequence.
