Authenticated Mobile Device Proxy Service.pdf

Abstract—In the current study we present a system that is capable to deliver proxy based differentiated service. It will help the carrier service node to sell a prepaid service to clients and limit the use to a particular mobile device or devices for a certain time. The system includes software and hardware architecture for a mobile device with moderate computational power, and a secure protocol for communication between it and its carrier service node. On the carrier service node a proxy runs on a centralized server to be capable of implementing cryptographic algorithms, while the mobile device contains a simple embedded processor capable of executing simple algorithms. One prerequisite is needed for the system to run efficiently that is a presence of Global Trusted Verification Authority (GTVA) which is equivalent to certifying authority in IP networks. This system appears to be of great interest for many commercial transactions, business to business electronic and mobile commerce, and military applications.

INTRODUCTION HE rapid progress in wireless communication systems, personal communication systems, and smart card Technologies has brought new opportunities and challenges to be met by engineers and researchers working on the security aspects of the contemporary communication technologies [1,2]. Having this technology available on the market, made a high demand for many applications and services to get restricted to certain physical devices. However, there are still significant difficulties to overcome when integrating mobile devices with embedded features into a ubiquitous computing environment. These difficulties include designing devices smart enough to collaborate with each other, increasing ease- of-use, and enabling enhanced connectivity between the different devices [3-6]. Public-key cryptography offers robust solutions to many of th
