Cryptographic hash functions are used extensively in information security, most notably in digital authentication and data integrity verification. Their performance is an important factor of the overall performance of a secure system. In 2005, some groups of cryptanalysts were making increasingly successful attacks and exploits on the cryptographic hash function, SHA-1, the most widely used hash function of the secure hashing algorithm family. Although these attacks do not work on SHA-2, the next in the series of the secure hashing algorithm family, the National Institute of Standards and Technology still believes that it is necessary to hold a competition to select a new algorithm to be added to the current secure hashing algorithm family. The new algorithm will be chosen through a public competition. The entries will be evaluated with different kinds of criteria, such as security, performance and implementation characteristics. These criteria will not only cover the domain of software, but the domain of hardware as well. This is the motivation of this thesis. This thesis will describe the experiments and measurements done to evaluate the SHA-3 cryptographic hash function candidates' performance on both ASIC and FPGA devices. The methodology, metrics, implementation details, and the framework of the experiments will be described. The results on both hardware devices will be shown and possible future directions will be discussed. / Master of Science

<p>GNU Radio is a software framework allowing easy creation of digital signal processing applications on a regular PC. The Universal Software Radio Peripheral (USRP) is a hardware component that can be used as a radio front-end and that is connected to a PC using USB. GNU Radio and the USRP together form a system for software-defined radio. The purpose of this thesis project have been to insert a large programmable logic circuit into the system that GNU Radio and the USRP together form. The goal of this is to make it possible to move parts of the signal processing away from GNU Radio and instead implement these parts in hardware. Possibilities for doing this has been analyzed and one of the possible systems performing this has been designed.</p>
