Software library of basic symmetric and asymmetric primitives of modern cryptography on embedded platforms
Miška, Matěj ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
This master thesis deals with a search of cryptographic primitives for embedded systems, which are tested on Raspberry Pi platforms and the results compared in the subsequent practical part. The content of the research is an explanation of the use of cryptography in information systems, an example of a protocol using cryptography in the energy sector, the selection of cryptographic primitives based on recommendations from security institutions, a description of Raspberry Pi embedded platforms and an introduction of cryptographic libraries providing tools to perform cryptographic operations. The theoretical part of the thesis results in an overview of the information needed to create a test tool. The subsequent practical part deals with the theoretical design of the required tool, the determination of the functions that the tool must have and the way of performing the testing. This is followed by a description of the choice of the programming language and development environment suitable for this work, together with a description of the internal structure of the developed application. The testing parameters are mainly the computational, memory and time requirements of the cryptographic primitives on the system. The paper concludes with methods of running and controlling the application, possible presentation of the measured results, the actual results of testing the selected embedded platforms and a discussion of these results.

Cryptography on an embedded platform
Korenčiak, Peter ; Hynčica, Ondřej (referee) ; Fiedler, Petr (advisor)
This bachelor thesis deals with adjusting parts of the public domain cryptographic library LibTomCrypt so that it can be used on an embedded platform Rabbit 3000. The hash functions MD5, SHA-1 and RIPEMD-128, the Blowfish cipher and CBC block cipher mode have been successfully ported to this platform. These algorithms have been analysed by measuring of the exectution time for the computational power requirements, especially with regard to the length of the input data. The abovementioned hash functions showed non-linear relationship between the execution time and the length of input, the graph of which is like that of a step function. The non-existence of the relationship to the data values was confirmed. The measurements with Blowfish cipher in CBC block cipher mode showed that inicialization of cipher is time consuming (it lasted almost one second on the hardware used) and that it does not depend on the keysize or length of input. The encryption and decryption itself showed a linear relationship to input data length. In the scope of this thesis there was also verification of correct function of SSL/TLS library from the producer of Rabbit microprocessor by creating a HTTPS server and verifying that secure connection with the web browser has been established. The library worked correctly according to manual without any significant problems.
