In cryptography module, a side-channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information which can be exploited to break the system. So the advanced many countries are conducting CMVP (Cryptographic Module Validation Program) to manage cryptographic module of safe IT product. But, systematic method that CMVP is such yet is unprepared.
