Cipher chips, such as microprocessors, are playing the important role in most cryptosystems, and protecting the data which is important.But since Side Channel Analysis is put forward, the security of cipher chip was met a severe challenge.Correlation photonic emission attacks (CPEA) is a new kind of method against cipher chips.Operating steps and the simulation result is given in the paper.First, A typical CPEA process is given, which is important for the simulation experiment.Then, the concept of correlation coefficient is given, and introduces a estimated method for correlation coefficient.There is a certain relationship between signal-noise ratio (SNR) and the correlation coefficient of CPEA.The last, the simulation results of CPEA against AES algorithm is given.
