Virtually all applications which provide or require a security service need a secret key. In an ambient world, where (potentially) sensitive information is continually being gathered about us, it is critical that those keys be both securely deployed and safeguarded from compromise. In this paper, we provide solutions for secure key deployment and storage of keys in sensor networks and RFID syst...

Embedded computing devices (such as actuators, controllers and sensors of various sizes) increasingly permeate many aspects of modern life: from medical to automotive, from building and factory automation to weapons, from critical infrastructures to home entertainment. Despite their specialized nature as well as limited resources and connectivity, these devices are now becoming increasingly pop...

With the improvement of telecommunication and wireless Internet-access technologies, smart mobile terminals have been extensively applied for mobile shopping. In this paper, PPM Model is taken as a theoretical framework and an empirical research method is employed to determine the antecedents influencing consumers’ decisions on migrating from PC-based shopping to mobile shopping. We found that ...

This paper analyzes the Improved Cellular Message Encryption Algorithm (CMEA-I) which is an improved version of the Telecommunication Industry Association’s Cellular Message Encryption Algorithm (CMEA). We present a chosen-plaintext attack of CMEA-I which requires less than 850 plaintexts in its adaptive version. This demonstrates that the improvements made over CMEA are ineffective to thwart s...

In this report, we describe mechanisms for platforms looking into a telecommunication cloud architecture we present focuses scenario we present. This report security mechanisms and protocols, leveraging existing standards and s applicable. In particular, our architecture uses TCG technologies for trust establishment in the deployment of operator virtual machines on shared resource platforms. We...

Since the birth of ARPANET and the first commercial applications of computer networks, through explosion of popularity of the Internet and wireless communications, we have witnessed increasing dependence of our civilization on information services of telecommunication networks. Their efficiency and reliability have become critically important for the well-being and prosperity of societies as we...

The universal mobile telecommunication system (UMTS) (3rd Generation Partnership Project [3GPP] TS 23.002, 2002) is a realization of third generation (3G) networks, which intend to establish a single integrated system that supports a wide spectrum of operating environments. Users have seamless access to a wide range of new telecommunication services, such as high data rate transmission for high...
