Advances in information and communication technologies lead to use of some new devices such as smart phones. The new devices provide more advantages for the adversaries hence with respect to them, one can define with-box cryptography. In this new model of cryptography, designers try to hide the key using as a kind of implementation. The Differential Computation Analysis (DCA) is a side channel attack on the with-box cryptography. The mentioned method influenced all with-box cryptography schemes when it was introduced. This attack is based on the software implementation of cryptography algorithms and is similar to the differential power analysis (DPA). In this paper, we introduce the principles of the DCA and also describe how one can use this attack to find the key of a with-box cryptography scheme.
Keywords: With-Box Cryptography, Block Cipher, Side Channel Attack, Differential Power Analysis, Differential Computation Analysis
