Security made easy: Achieving user-friendly communication protection in ad-hoc situations

Mobile applications dealing with ad-hoc situations do have their own challenges such as a reasonable short time for interaction and limitations of available technology. A secure yet user-friendly solution for protecting wireless communication therefore is a service enabler for mobile business. This paper discusses the drawbacks of existing security concepts and proposes a framework on application level to help developers improving user acceptance. Additionally, we present the evaluation results of the prototype which leverages the user´s common spatial context by integrating him into the device authentication process.
