Authentication Using Lightweight Cryptography
Člupek, Vlastimil ; Uchytil, Stanislav (referee) ; Dostál, Otto (referee) ; Zeman, Václav (advisor)
The dissertation thesis deals with cryptographic protocols for secure authentication of communicating parties, which are intended primarily for low-cost devices used in Internet of Things. Low-cost devices represent computationally, memory and power constrained devices. The thesis focuses mainly on the possibilities of using mathematically undemanding cryptographic resorces for ensuring integrity of transmitted dat, authenticity of and secured transmission of data on low-cost devices. The main goals of the thesis focus on the design of new advanced cryptographic protocols for ensuring integrity of transmitted data, authenticity, confidentiality of transmitted data between low-cost devices and authenticity with non-repudiation of done events. The thesis describes proposal of three authentication protocols, one unilateral authentication protocol and two mutual authentication protocols. The thesis also describes proposals of two protocols for secured transmission of data between two devices, one protocol without a proof of receipt data and one protocol with proof of receipt data. In this thesis is also performed a security analysis and a discussion to proposed protocols.

Physical unclonable functions
Hegr, Vojtěch ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
The theme of the thesis is Physical Unclonable Functions (PUF). The following objectives were assigned: to provide a literature research concerning PUFs, to perform a property analysis to select appropriate type of PUF for implementation and to realize an authentication cryptosystem based on the chosen PUF. Based on the research, the cryptosystem was designed based on ring oscillator PUF. The proposed cryptosystem is tested in several scenarios with the maximal rate of successful authentication of 81%. The cryptosystem also allows to be used for device identification. Furthermore, the results were discussed and suitable improvements of design was proposed. Besides the cryptosystem itself, the thesis also introduced a unique comparison of existing types of PUFs.
