Use of Advanced Encryption Standard to Enhance the Performance of Geo Protocol in Location Based Network

Wireless technology is the default access technology in many services like mobile commerce, sending emails, banking application, military applications, etc. In such applications, we need Secure Communication and it is possible only when we secure data. Data encryption algorithms are used to secure such data. Most of the existing data encryption techniques are location-independent. Data encrypted with such techniques cannot restrict the location and time of data decryption. And hence the concept of Geo-encryption or Location Based Data Encryption is evolved. Much research has been done on location based data encryption algorithms and techniques. In this paper, we are going to investigate the weaknesses of Geo-encryption algorithms and try to improve them so as to enhance the performance of the Geo - protocol. For this purpose, we make the use of Advanced Encryption StandardGeo-encryption with Dynamic Tolerance Distance (AES-GEDTD) instead of Data Encryption Standard-GEDTD (DES-GEDTD). We also demonstrate the performance of the proposed approach over the existing one.
