Using A Two Dimensional Colorized Barcode Solution for Authentication in Pervasive Computing

The task of establishing secure communication in a wireless pervasive computing environment faces several challenges. One of the most critical is determining the authenticity of the parties wishing to communicate. An existing method of enabling authenticated key agreement involves using a two-dimensional visual code system with digital camera enabled devices as a way of demonstratively identifying entities. This paper seeks to extend that solution by colorizing the code system, thereby extending the amount of data which can be carried by a visual tag, and thus reducing the necessary size of such tags. This create images more easily recognized by the devices establishing secure communication in wireless pervasive computing environments. A detailed explanation of an implementation of this method is presented, along with performance evaluation and analysis
