Abstract

Analiza postojećih rješenja podatkovne enkripcije s niskom potrošnjom energije. Korištenjem otvorenih alata osmisliti algoritam enkripcije koji će se moći implementirati u sustavima s ograničenim energetskim resursima. Implemetirati predloženo rješenje na razini višeg programskog jezika, te na razini mikrokontrolera. Usporediti i verificirati funkcionalnosti predloženog rješenja.

Abstract (english)

The aim of this study was to find a cryptographic algorithm suitable for use in systems with very low energy consumption such as wireless sensor networks. As the solution, open-source algorithms Blowfish and Twofish were suggested. They were described in details. Overview of previous work has demonstrated their superiority over the other most famous cryptographic algorit- hms in terms of efficiency. They were implemented in levels of C programming language and microcontroller. LPC2103 — the microcontroller of Keil MCB2103 Evaluation Board was used. Implementation on Intel Core i3-2310M 2.10 GHz processor showed that Blowfish’s initialization process lasts 7.954 times longer and encryption process 3.117 times shorter then Twofish’s. Measurement of implementation on LPC2103 microcontroller showed that Twofish dissipates 5.119 times more energy and uses 4.318 times less RAM memory. The results were analyzed in relation to properties of both algorithms.
