The Cost of Security in Mobile Devices

Abstract

The mobile devices have rapidly evolved, they have become into the platform of communication and computation preferred by people. Nevertheless, the growing popularity of these devices is not always positive because they threaten the safety of their users. If we consider that the technological limitations are still present in these mobile devices and that most of them have safety mechanism which based their operation on cryptographic techniques, so we can expect some restrictions at the moment of attempting to protect the applications and data handled by these devices. 

For this reason, this article investigates the commitment between: safety, performance factors and the energy that these devices consume at the moment of being  pplied on mobiles and digital assistances. The obtained results show that safety in the mobile applications is not free and that a good implementation requires a careful selection of each parameters used by cryptographic mechanisms. Based on this study, we have also proposed a “framework” of safety easy to use for the development of mobile applications in J2ME.
