Recent technological advances have enabled a great growth in mobile devices utilization on the last few years. Consequently, there has also been an increasing demand for secure applications in this environment. Security in standard wired networks is already a theme of known complexity. The mobile environment, however, introduces further complications, such as an open communication medium, that makes data interception easier, and the restrictions imposed by mobile devices, which usually have fewer computational resources, and therefore can have restrictions while using certain sophisticate security algorithms.This work proposes an adaptation for security methods on mobile environments; in witch the security methods are chosen dynamically according to the semantic worth of transmitted data. The goal is to realize transmissions using security methods consistent with the worth of sent data. This way, it's possible to use less computational resources in communications that don't need special security configurations and use them on communications that really need to.
