Side channel analysis on AAᵝ cryptosystem and a signing scheme based on bivariate function hard problem and discrete logarithm problem

This study has two main parts. The first part discusses side-channel attack on the AAb cryptosystem. The encryption scheme was introduced in 2012. Hence this attack is aimed to address new rooms for improvements for AAb . Side-channel attack is an attack on the implementation of a cryptosystem by co...
