Seminar paper from the year 2008 in the subject Computer Science - Commercial Information Technology, grade: 1.3, University of Regensburg, language: English, abstract: Cryptographic algorithms have nowadays serious impact on many fields of modern life. A goodexample is the SSL technology, that consists of both symmetric as well as asymmetric cryptography.It is used in thousands of websites like online banking websites to secure transfered data.For the developers of such applications the performance of employing cryptography may be acrucial factor to the success of the complete product. Normally a software developer utilizescryptographic operations by the usage of precast cryptographic libraries. Therefore, it is interestingto analyze the speed of cryptographic libraries which implement abstract cryptographicalgorithms. In the following, we describe our benchmarking of various cryptoalgorithms in differentcryptolibraries in different languages on a 32-bit system. In the first part, we outline ourpreparatory work and our considerations on setting up a fitting benchmarking environment. Withthis test environment we conducted the benchmarking of seven JAVA cryptolibraries, namelySUN-JCE, Flexiprovider, Bouncy Castle, Cryptix Crypto, IAIK-JCE, GNU crypto and RSAJSafe. Additionally, we benchmarked RSA BSafe, a cryptographic library, which is writtenin C++, to isolate the influence of the JAVA virtual machine abstraction layer on cryptographicperformance. In the second part, we present a condensed illustration of the benchmarking resultsand our interpretation, for symmetric cryptography, asymmetric cryptography, the generation ofhash based massage authentication codes and digital signatures. These results reveal remarkabledifferences in speed between the algorithms as well as between the different implementations.Also the choice of the underlying operating system has influence on the execution speed of thecryptographic code. In this work we demonstrated that software developers could gain a multipleof the execution speed of the cryptography utilizing parts of their programs just by a wise selectionof cryptographic algorithms and libraries. Furthermore our work can help as a guideline fordeveloping a generic benchmarking model for cryptoalgorithms.
