Abstract:	Šifriranje je najpogostejši način varovanja podatkov med prenosom preko javnih kanalov. Najpogosteje uporabljamo standard AES; ta spada med simetrične bločne šifre, ki za zagotavljanje zaupnosti, celovitosti in overjanja uporabljajo načine šifriranja. V magistrski nalogi smo s statističnimi metodami primerjali hitrosti različnih implementacij simetričnih bločnih šifer in načinov šifriranja. Ugotovili smo, da je pospešeno šifriranje oz. dešifriranje s šifro AES v povprečju 11,1-krat oz. 14,9-krat hitrejše kot nepospešeno. Nepospešeni AES je tudi hitrejši od ostalih primerljivih šifer. Najhitrejši AEAD-način šifriranja je OCB, med osnovnimi pa CTR pri šifriranju in CBC pri dešifriranju.

Title:	Performance analysis of symmetric block ciphers
Abstract:	Data encryption is the most common way to secure data during transmission over public channels. Mostly used is standard AES, which is a symmetric block cipher. To provide data confidentiality, integrity and authentication block ciphers use modes of operation. In the scope of the thesis statistical methods were used to compare the performance of different implementations of symmetric block ciphers and modes of operation. We have found hardware accelerated AES to be 11.1 and 14.9 times faster than non-accelerated for encryption and decryption respectfully. Non-accelerated AES was the fastest compared to other comparable ciphers. The fastest AEAD mode of operation is OCB, while CTR and CBC are the fastest common modes for encryption and decryption respectfully.
Keywords:	symmetric ciphers, block ciphers, modes of operation, AES, performance
