Application for secure data storage for mobile devices
Kocáb, Marek ; Martinásek, Zdeněk (referee) ; Mácha, Tomáš (advisor)
This bachelor’s thesis is focused on the creation of application for secure data storage for mobile devices. The paper theoretically describes operating system according to users popularity and programming languages. The following section explains AES encryption standard and its principle of data encryption and decryption. In the practical part is created a PINapplication programm. The application allows user to store sensitive data using chosen password. It is possible to save new data or erase current data. These data are encrypted by mentioned AES standard. The application is programmed in Java language with the version for mobile devices (J2ME).

Smartcard authentication
Juras, Stanislav ; Burda, Karel (referee) ; Hajný, Jan (advisor)
The master’s thesis outlines the problem of authentication. It describes authentication factors like ownership, knowledge and inherent. There are described properties of each of that. Authentication based on ownership focuses on authenticators - the smartcards. The thesis also describes different types of smartcards (contact, contactless and hybrid smartcards) and refers to their basic properties. Emphasis is placed on the description of contact and contactless smartcard, specifically focusing on .NET smartcards. It describes their internal components such as memory (RAM, ROM, EEPROM), crypto processor etc. Smartcards are also examined in terms of support for cryptographic primitives. The thesis also introduces the cryptographic methods and principles describing symmetric and asymmetric ciphers. Symmetric ciphers are divided in to stream and block ciphers. There is description of asymmetric cipher, digital signature etc. This work also touches on the fundamental principles required for safe programming. Part of this work is also practical implementation (programs). Practical part aims to implement the communication between the user and AC (Access Control) AASR system. The first suite of applications provides encrypted communication between the PC and smartcards. These applications should create on smartcard services that will be able to perform operations on the client side, which are necessary to authenticate in the AASR system. The paper also presents algorithms for working with big numbers - addition, subtraction, multiplication, and Montgomery's algorithm for multiplication. The second application implements the functionality of AC components (Access Control). This functionality is for example – authenticate received token, digital signature authentication, generating random numbers, logging etc.

Implementation of Encryption Algorithms in VHDL Language
Fruněk, Lukáš ; Fukač, Tomáš (referee) ; Kořenek, Jan (advisor)
The thesis deals with the design and implementation of the encryption algorithms DES and AES, operating in the CTR mode. The designed modules are implemented in the VHDL language and are mapped in the FPGA Intel Arria 10 SX 480. Algorithms are optimized for maximum throughput using loop unrolling and inner pipelining. The encryption module for DES reaches throughput of 26.2 Gbit/s with the circuit operating 410 MHz, and the module for AES reaches throughput of 34.6 Gbit/s with the circuit operating at 271 MHz. The reached throughput is in the order of thousand times faster than of the same encryption algorithms implemented in software for built-in microprocessors.
