Differential Power Attack Analysis of Ultra-Lightweight Block Cipher BORON

Most of cryptographic devices are CMOS based microelectronic circuit. These circuits are mean to be dump dedicated software code to work for the specific application. With growth of Ubiquitous computing, these microelectronics circuit are become smaller and smaller in size and also it is expected that every microelectronic circuit should consume less power to perform task. The power consumption of these CMOS based circuit is influence by activity of individual component of the circuit. CMOS based cryptographic devices holding encryption standard i.e. secret information which can be leak through the power consumption of the device. It has been found that it is possible to retrieve secret key of algorithm by appropriate analysis of crypto-processor's power consumption. This study of crypt-analysis comes under the Side Channel Crypt-analysis. Differential Power Attack (DPA) is most powerful attack which reveals the secret information of the algorithm. This paper propose the DPA on ultra-lightweight block cipher BORON which shows that BORON block cipher is vulnerable to power attack and to avoid DPA attack on BORON proper masking scheme has to study. This paper followed the computer based approach to demonstrate DPA attack on Block Cipher BORON.
