Limited computational power imposes new challenges during the implementation of security and privacy solutions for mobile devices. The choice for the most appropriate cryptographic algorithm for each mobile device has become a critical factor. In this paper, we present an approach for performance evaluation of cryptographic algorithms for mobile devices. A tool called PEARL (PErformance evaluAtor of cryptogRaphic aLgorithms for mobile devices) is also introduced in this work to validate the approach. This tool collects and analyzes information related to executions of the cryptographic algorithms in the mobile devices. Moreover, PEARL allows evaluating the performance of symmetrical and asymmetrical cryptographic algorithms, and hash functions for the J2ME platform.
