PEARL: a PErformance evaluaAtor of cRyptographic aLgorithms for mobile devices

draft PDF

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. To validate the approach, a tool called PEARL (PErformance evaluAtor of cryptogRaphic aLgorithms for mobile devices) is introduced. This tool collects and analyzes information related to the executions of the cryptographic algorithms in the mobile devices. PEARL also allows evaluating the performance of symmetrical and asymmetrical cryptographic algorithms and hashing functions for the J2ME platform.

MobiS: A Solution for the Development of Secure Applications for Mobile Devices

Draft PDF

With the mobile computing evolution, portable devices have emerged in the market with the possibility of connection to IP networks using wireless technologies. The migration from fixed terminals to wireless mobile devices and the increasing availability of information for such devices impose new challenges in the development of applications. The security and the portability are examples of these challenges that constitute the motivation for this work. Our main goal is to introduce a solution, called MobiS (Mobility and Security), to the development of secure applications for data transmission using wireless technologies.

FramePersist: An Object Persistence Framework for Mobile Device Applications

Draft PDF

Traditional requirements for persistence layers do not consider limitations of the development platforms available for mobile devices. In order to facilitate the development of applications, which need to store data, for mobile devices, these traditional requirements are reevaluated in this paper and a framework for object persistence is proposed. This framework, called FramePersist, is constructed based on the concept of object serialization and allows to persist and to search objects efficiently. Mapping rules of objects for persistence are presented together with a case study using the Symbian OS native file systems.
