Secure applications with microcontrollers
 Sobotka, Jiří ; Herman, Ivo (referee) ; Balík, Miroslav (advisor)
This thesis deals with problematics of secure operations of microcontrollers. During long-term use, the microcontrollers can be affected by error or malfunction. The aim of this thesis is to describe the types of errors which can affect processors, cause of creation of these errors and possibilities of preventing malfunctions in microcontrollers. There is many problems connected with operation of microcontrollers, therefore there are many methods to prevent these problems. First part of this thesis deals with description of types of mistakes and with attempts of theirs modelling. Second part of this thesis narrate possibilities of preventing each type of mistake during designing the system or during operation of microcontroller and explaining methods of fault toleration by using redundant circuits in case of hardware fault and by modifying source code in case of software faults. In third part the hazard analytical methods are described. The recognition of events able to damage the system has high importance. The risk analysis takes place during developing and during operation of the system. Fourth part is trying to describe some of the processor testing techniques as main method of finding errors before operating use of microcontroller. Last part attempts to practical draft of testing algorithm for chosen microprocessor and application of one of analytical techniques.
