摘要
According to an aspect, a power line communication device includes a power line communication unit, a process unit, a waveform acquiring unit, a storage unit, a comparing unit, and a security level setting unit. The power line communication unit performs power line communication based on a communication signal superimposed on a carrier wave transmitted via a power line. The waveform acquiring unit acquires a waveform of the communication signal included in the carrier wave transmitted via the power line of the commercial power source. The comparing unit compares waveform information stored in the storage unit with waveform information acquired by the waveform acquiring unit at the time of requiring the process of the process. The security level setting unit changes the security level based on the comparison result by the comparing unit.
