The mobile telecommunication industry is becoming one of the most important industries in the world. In the spectrum of wireless communication technologies, digital cellular telecommunication using the Global System of Mobile Communication (GSM) standard has enjoyed the fastest growth rate. This paper attempts to examine GSM driving factors on a national level. For this purposes, it uses system...

A secure roaming protocol for mobile networks is proposed. Roaming has been analysed in some schemes from the security point of view; however, there are vulnerabilities in most of them and so the claimed security level is not achieved. The scheme offered by Wan et al. recently is based on hierarchical identity-based encryption, in which the roaming user and the foreign network mutually authenti...

Disaster management using mobile telecommunication networks provides a new and attractive possibility to save human lives in emergencies. With this contribution, we present a possible disaster management system based on mobile telecommunication. In order to use such a system in the real world, security requirements such as availability, accountability, integrity and confidentiality have to be e...

Following the commercial deployment and worldwide success of 2 generation mobile telecommunication systems, standardization bodies, industry partners and regulatory fora from around the globe joined forces in producing the standards for 3 generation mobile telecommunication systems. In parallel, the academic research community has been gradually shifting its focus in defining the scope of 4 gen...

INTRODUCTION RAPID advancement of semiconductor integratedcircuit technology has reduced the cost of mobile telecommunication terminals year by year. The global systems for mobile communications (GSM),1) which was standardized mainly by European countries, has enhanced the large scale integration of radio-frequency circuits because mobile telecommunication systems of European countries do not r...
