Postquantum Cryptography on the FPGA Platform
Dobiáš, Patrik ; Jedlička, Petr (referee) ; Malina, Lukáš (advisor)
This master thesis deals with the hardware implementations of post-quantum cryptogra- phy schemes on FPGA platforms. After the initial comparison of the candidate schemes for NIST standardization and the analysis of the previous work focusing on these schemes, Crystals-KYBER scheme was chosen and implemented. All scheme algorithms have been implemented inside a single component, minimizing resource utilization. The results of this implementation were analyzed and compared with the existing implementations. At the end of this work, the implemented scheme was deployed on Virtext UltraScale+ and tested for the use during mutually authenticated key exchange (AKE).

Cryptanalysis of modern cryptographic devices
Fördős, András ; Člupek, Vlastimil (referee) ; Martinásek, Zdeněk (advisor)
The thesis focuses on power analysis of modern cryptographic modules. The first part contains a brief introduction to the topic of the power side channel and basic methods of analyzes. The text describes the process of comparison of modules and a short description of devices found. In the practical part two modules has been selected for the implementation of the encryption algorithm AES-128. The first module was the chip card Gemalto .NET v2 and the second one was the Raspberry Pi. A workplace has been created for these modules which allowed to measure the power consumption of the algorithm AES. Differential Power Analysis has been made using the captured results. In its conclusion the work presents the results in tables and samples of source codes. Graphs were made from the results captured on the Raspberry Pi and from the results of the Differential Power Analysis.

Lightweight Cryptography
Šalda, Jakub ; Palovský, Radomír (advisor) ; Ivánek, Jiří (referee)
In the bachelor thesis Lightweight cryptography I describe the basics of light cryptography, analyze and compare selected lightweight symmetric ciphers. Lightweight is about trade-off between low-cost, security and performace. There are many lightweight ciphers designes, therefore I chose nad explored some of those from the point of view of their features, hardware implementation, performance and security. Analyzed ciphers are in total of fifteen and include E0, A5/1, GRAIN, Trivium, LED, SKINNY, RECTANGLE, SPARX, mCrypton, PRESENT, SIMON and SPECK, XTEA, SEA, LBlock and CLEFIA. I have come to the conclusion that the stream cipher GRAIN is very fast and safe. Block ciphers LED and SKINNY are well secured and SIMON and PRESENT hardware-efficient. With the increased use of constrained devices, it is also necessary to keep up with security, so lightweight cryptography could have a great future ahead.
