Luo Xiao-fei · Journal of Chengdu University of Information Technology · 2012
The Camellia algorithm and Differential Power Analysis(DPA) methods are briefly introduced.According to DPA attacking method on Camellia algorithm has the problems of large quantity samples and low efficiency,a combination attack method is put forward.The power consumption traces were collected in simulation hardware platform for same key with different plaintext,and the attack point was determined with Simple Power Analysis(SPA),then the secret information could be obtained with DPA.Experimental results show that with 10000 power traces can retrieve Camellia algorithm key and prove that the combination method of attack Camellia algorithm is feasible and effective.
