Security Adaptation Components for Mobile Communication

Mobile computing and communication develops into an important factor in business, but it is accompanied with new security threats. The main problem lies on the one hand in the heterogeneity, dynamics and scarcity of the resources and on the other hand in the additional information like user location. In this paper, we investigate some issues concerning security of mobile computing systems, which are new to consider and we show a basic characteristic of these security issues, adaptability. The conditions of the mobile environment like the user location or network bandwidth are changing, but traditional security mechanisms are very static. We propose a "Security Adaptation Component" (SAC) introduced at the “base station“ and the „mobile unit“, which serves the adaptation of security issues to the particular mobile communication environment.
