Side channel attack in cryptanalysis of symmetri and asymmetric schemes

The work summarizes author's three main results during the doctoral studies published at SAC '06 and CHES '09 conferences and the journal IET Information Security. The first two results are the side channel attacks on asymmetric schemes RSA and DSA. They are both based on the theory of lattices and are motivated by modern technologies such as Intel Pentium 4 HTT processor and the electronic passport. The last result is more technology related. It describes the method that provides optical side information and that was empoyed for the first time for the cryptanalytic purposes by the author. As an application, an attack on symmetric cipher AES running on a simple and widespread microcontroller PIC16F84A is presented
