Study and Implementation of 3G Mobile Security

In the last decade there has been an exponential rise in use of mobile devices. 3G is the latest mobile technology that is currently in widespread use. The Universal Mobile Telecommunications System (UMTS) is the most popular third generation mobile communication systems, which reposes on the popularity of the ‘second generation’ GSM system by introducing high quality services while retaining its essential and robust security features. Wireless communication is less secure, and mobility entails higher security risks than stationary devices. Security is the foremost concern in today’s mobile communication systems. Latest security mechanisms are needed to protect the singular features introduced in 3G technology. The security framework for 3G mobile networks is considered, and the various protocols for protection of the network access interface are studied and analyzed

Security architectures in mobile integrated pay-TV

This paper presents the design and describes the advantage of the state-of-the-art Mobile Integrated Conditional Access System (MICAS) concerning interoperability, personalisation, security and operational costs in Pay-TV systems. The Message Handling Subsystem is proposed and outlined together with ‘Follow-Me’ service, which proposed herewith to extend mobility and personalisation concepts on Pay-TV service

Securing the Internet of Things Infrastructure - Standards and Techniques

The Internet of Things (IoT) infrastructure is a conglomerate of electronic devices interconnected through the Internet, with the purpose of providing prompt and effective service to end-users. Applications running on an IoT infrastructure generally handle sensitive information such as a patient’s healthcare record, the position of a logistic vehicle, or the temperature readings obtained through wireless sensor nodes deployed in a bushland. The protection of such information from unlawful disclosure, tampering or modification, as well as the unscathed presence of IoT devices, in adversarial environments, is of prime concern. In this paper, a descriptive analysis of the security of standards and technologies for protecting the IoT communication channel from adversarial threats is provided. In addition, two paradigms for securing the IoT infrastructure, namely, common key based and paired key based, are proposed

Quantum cryptography: a practical information security perspective

Quantum Key Exchange (QKE, also known as Quantum Key Distribution or QKD) allows communicating parties to securely establish cryptographic keys. It is a well-established fact that all QKE protocols require that the parties have access to an authentic channel. Without this authenticated link, QKE is vulnerable to man-in-the-middle attacks. Overlooking this fact results in exaggerated claims and/or false expectations about the potential impact of QKE. In this paper we present a systematic comparison of QKE with traditional key establishment protocols in realistic secure communication systems.Comment: 5 pages, new title, published version, minor changes onl
