Hiding of current consumption
Hirš, David ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
Power analysis presents the typical example of successful attacks against trusted cryptographic devices such as smart cards or embedded devices. Nowadays, the popularity of Internet of Things (IoT) is growing therefore, designers sould implement cryptographic algorithms with countermeasures in order to defend against these types of attacks. The bachelor's thesis focus on the implementation of ultra-lightweight block cipher PRESENT and execution of Simple power analysis and Differential power analysis to reveal the secret key. Power analysis is firstly performed on cipher PRESENT with no implemented countermeasures and the attack was successful. Then the countermeasures were implemented and there were no leakage about the secret key. The countermeasures are using the hardware randomization of FPGA boards.

Intrusion prevention system based on Raspberry Pi
Hirš, David ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
The number of discovered vulnerabilities rapidly increases. For example in 2019 there were discovered 20 362 vulnerabilities. The probability of cyber-attacks realization is high. Therefore it is necessary to propose and implement automated and low-cost Intrusion Prevention or Intrusion Detection Systems (IPS/IDS). This implemetation can focus on home use or small corporate networks. The main goal of the system is to detect or mitigate cyber-attack impact as fast as possible. The master's thesis proposes IPS/IDS based on Raspberry Pi that can detect and prevent various cyber-attacks. Contents of this thesis are focus on description of cyber-attacks based on ISO/OSI model's Link and Network layers. Then there is description of IPS/IDS systems and theirs open source representatives. The practical part is focus on experimental workspace, hardware consumption of choosen detection systems, cyber-attacks scenarios and own implementation of detection program. Detection program is based on these chosen systems and puts them together to be easily manageable.

Proposal Of Cyber Threat Detector Using Raspberry Pi
Hirš, David
Nowadays, the number of discovered vulnerabilities increases rapidly. In 2019, the 20,362 vulnerabilities were discovered. Therefore, the probability of cyber-attacks realization and theireconomic impact are real. Currently, it is necessary to propose and implement automated and lowcostIntrusion Prevention Systems (IPS) that is applicable for home use or small corporate networks.The main goal of the system is to mitigate cyber-attack impact as fast as possible. In this article, wepropose IPS based on Raspberry Pi that can detect and prevent many various cyber-attacks.
