Side channels fundamentally changes the view of the cryptographic system security in cryptography. It is not enough to analyze the security algorithm only from a mathematical point of view using abstract models but it is necessary to focus on the implementation of the algorithms. The introduction of the thesis deals with the basic terms, principles of side channel attacks and basic clasification of side channels. The following chapter describes the objectives of the thesis. The main goal of the thesis is to propose and experimentally verify a new power analysis method whish will use the neural network. This main goal was based on the realized analyzes presented in the following chapters. These chapters contain a detailed analysis of currently used power analysis and analysis of AES encryption algorithm. AES was selected becouse the algorithm is resistant to the conventional cryptoanalysis. The following section describes the experimental results of the optimization of existing methods, the influence of the parameters affecting power consumption and the results of the proposed analysis using neural networks. This section includes the discussion of the results. This type of side channel attack has not been published yet thus it is a completely new idea. The final goal of the thesis was to summarize the possible countermeasures protecting against the side channel attacks.
