Attribute Authentication on Android Platform
Strakoš, Jan ; Ricci, Sara (referee) ; Malina, Lukáš (advisor)
This master’s thesis focuses on implementation of ABC (Anonymous attribute-based credential) pilot system on the Android platform. The support for attribute authentication on the Android platform is very weak in terms of the number of implementations and needs a special attention. The theoretical part of the thesis describes the cryptographic support on the Android platform, the use of the Android Native Development Kit (NDK) and the Host-Card Emulation (HCE) service. The theoretical part of the thesis also includes a description of attribute authentication schemes, including a pilot RKVAC system. The practical part describes the implementation of the RKVAC system on the Android platform along with the implementation of a custom cryptographic kernel based on the native MCL cryptographic library. The practical part of this thesis describes implementation proces of RKVAC system on Android plaform, that uses native cryptographic library MCL. The final part shows the results of time, memory and computation difficulty of developed applications.

Security of authentication protocols
Tran, Minh ; Člupek, Vlastimil (referee) ; Dzurenda, Petr (advisor)
This thesis deals with the security of authentication protocols. The aim of the thesis is to analyze current security threats and attacks on current card systems mainly JavaCard and Mifare. And then to create a mobile application using Android platform with NFC and HCE functions, which realises the founded attacks. These attacks are relay attack and card cloning. Mobile side of the application is written in Kotlin programming language and server side in JavaScript, EJS and CSS. In the end attacks on EMV and access system of an unnamed university are demonstrated.

Authentication in the IoT
Drápela, Roman ; Malina, Lukáš (referee) ; Dzurenda, Petr (advisor)
Bachelor thesis focuses on authentication in the IoT. Some of the authentication protocols from the area of IoT are introduced at the beginning of the thesis. Next part of the thesis describes the NFC and BLE technologies, which can be applied in the IoT. Multi-device protocol is implemented using different devices (PC, mobile phone, SmartWatch). This protocol enables autentication based on the processes above the elliptic curves. Two sets of measurements (simulated and practical) are provided. In the final part of the thesis all the results are assessed.

Security system using smart devices
Klasovitý, Kristián ; Malina, Lukáš (referee) ; Dzurenda, Petr (advisor)
This thesis deals with the implementation of authentication system, where users can use theirs Android mobile phone and WearOS smart watch to log in. This system uses a zero-knowledge protocol based on Schnorr protocol and it provides authentication of a server and of multiple devices of the user. The system uses technologies NFC, Bluetooth, HCE and it is implemented in Java. For some of the computation on mobile devices the system uses native functions written in C.

Advanced security applications for Android
Orgoň, Marek ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
The thesis deals with security of the Android operating system, both general security features and options for storing sensitive data. The suitability of Android KeyStore for storing sensitive data and the possibility of using the secure element for safe application calculations and smart card emulation are discussed. Using Host-based Card Emulation for contactless smart card emulation is discussed. The performance analysis of modular arithmetic operations for numbers with high bit length is examined. Following these analysis, an implementation of application for software contactless smart card emulation of HM12 and HM14 cryptographic protocol is proposed. And an implementation of application for verifying smart cards with these protocols is proposed. Also scheme for secure storage of sensitive data is proposed.
