....and our modified architecture. Finally, conclusions and a brief outline of future work are given in Section 5. 2. RELATED WORK Various researchers have investigated the potential for both invasive and non invasive attacks against smart cards. An overview of these techniques is presented in [4, 15]. In particular, the retrieval of secret information from a smart card through its leakage called side channel analysis poses an important class of attack. Analyzing the power profile of an encryption process is one of the popular side channel attacks. Kocher et al. 7] provide a detailed ....

....to statistical treatment using large samples. While complete protection is difficult to achieve using such a counter measure, it could make it infeasible for an attacker to break the key. The second counter measure technique is to modify the underlying software implementation or algorithm [3, 4, 5]. For instance, the use of non linear transformations of S box operations is proposed in [5] to avoid some DPA attacks. However, it is observed in [4] that software counter measures may be difficult to design. The third form of countermeasure involves replacing some of the critical instructions ....
