Implementation of AES algorithm to overt fake keys against counter attacks
S Savitha, S Yamuna · 2016
This paper presents an approach to overt the cryptographic key, when there is any counter attacks so-called side-channel attacks (SCAs) are applied in order to break the security of AES-128. The algorithm was executed using ModelsimSE6.5e and various analyses were done in Xilinx 14.2 and MatLabR2014a. SCAs are based on examining the correlation produced between the data and operations performed by the device and its actual power consumption. Traditionally, measures have been taken to reduce such correlations by making parameters independent. On the contrary, the proposed approach introduces few modifications in the AES algorithm. These changes aim at masking the true key by reinforcing the correlation coefficient in such a way that the attack leads to a false key and the attacker is misguided with a false key. Experimental results show the strength of the proposed system, which is capable of successfully hiding the true cryptographic key.
