In this masters's thesis is closely studied questins of current (power) side channel. It deals with attack upon this type of side channels and methods, which can this channel analyse. Also two methods of measurements, which make possible successfully attack, are presented here. Below the work describes progress, which was used for analyse current side channel of chip PIC16F84A. This chip, which was plugged in the circuit in agreement with diagram introduced here, processes step by step variety of programs implementing always other operation, which matches concrete used instruction. In corresponding chapters are introduced resulting values and graphs, which was obtained by measurement.

This thesis investigates the development of an animatronic robot with the objective of showing how modern animatronic models created as special effects have roots in models created during the scientific and mechanical revolution of the 17th and 18th centuries. It is noted that animatronic models that are available today have not been described in any great detail and most are covered by industrial secrecy. This project utilises technologies developed during the latter part of the 20th century and into the beginning of the 21st century to create the design of the animatronic robot. The objective of the project is to bring effective designs for animatronic robots into the public domain. The project will investigate a large variety of different mechanisms and apply them to various functioning parts of the model, with the design and method of each of these functions discussed. From this, one main part of the project, the jaw, will receive the focus of construction. Once the construction is complete this will be evaluated against what improvements and changes could be made for future iterations, with a revised design produced based on what has been learned.

This thesis deals with electromagnetic analysis and applications of electromagnetic side channel. The first and second part describes the basics of cryptography, function of cryptographic module and side-channel attacks. The third part discusses the electromagnetic analysis, construction of probe, a description of the laboratory workplace, the electromagnetic emission of PIC16F84A, AES and preparation for laboratory measurements. The fourth part describes specific laboratory measurements and extracting the useful signal. In the fifth part of the thesis presents the results of processing the measured values, the outputs generated by scripts and found the link between measured curves and AES encryption key. In the sixth part of the thesis are analyzed the basics of defense against side channel attack.

This Master Thesis deals with the side channels, AES encryption algorithm and the use of neural networks to obtain the encryption key. The first part of this work is focused on the basics of cryptography and attacks on cryptographic module. The second part is focused on electromagnetic side channel attack on PIC16F84A microcontroller with embedded AES algorithm. In this section, the Master Thesis tries to analyze electromagnetic emissions of operation S-Box in AES algorithm and try to find sensitive information to use neural network identify encryption key of the AES algorithm. In conclusion is described the software source code to determine the encryption key, summarized results and discussed ways to defend against electromagnetic side channel attack.

Issues of this thesis are focused on side-channel cryptanalysis. Particularly attention is paid to differential power analysis, when is simulated an attack on the cryptographic module for different conditions and for different structural features of this module. As the cryptographic module is used a PIC microcontroller, which is operating with AES symmetric encryption algorithm. For this purpose, a design of experimental printed circuit board was created. Then, this PCB was equipped only with the necessary components for the function of the cryptographic module. Cryptanalysis is aimed on current consumption of crypto module that is caused by execution of AddRoundKey instructions. Power consumption of PIC microcontroller is measured in depending on the size of power supply voltage, size of serial resistor, size of bypass capacitor, and this thesis also examines the influence of ambient temperature on power consumption of PIC. The measured values are graphically presented and then discussed.
