Liberalizing basic telecommunications : the Asian experience
The authors examine the liberalization of the basic telecommunications sector in Asian countries with a view to identifying good policy and determining how multilateral negotiations can promote it. They find that most Asian governments, despite the move away from traditional public monopolies, are still unwilling to allow unrestricted entry, eliminate limits on private and foreign ownership, and establish strong, independent regulators. But where comprehensive reform has been undertaken-including privatization, competition, and regulation-the availability of main lines, the quality of service, and the productivity of labor are significantly higher. Somewhat surprisingly, little unilateral liberalization has occurred since the last round of telecommunications negotiations under the General Agreement on Trade in Services (GATS). The new round therefore faces the challenge of not merely harvesting unilateral liberalization, as in the past, but of negotiating away existing restrictions. Since quantitative restrictions on the number of telecommunications service suppliers are pervasive, deepened GATS rules could help ensure transparent and nondiscriminatory allocation of licenses. There may also be a need to sharpen the regulatory principles established in the last round and to create rules that safeguard not only the rights of foreign suppliers but also those of consumers.Decentralization,ICT Policy and Strategies,Environmental Economics&Policies,Economic Theory&Research,International Terrorism&Counterterrorism,ICT Policy and Strategies,Economic Theory&Research,Environmental Economics&Policies,Knowledge Economy,Education for the Knowledge Economy
Trade imbalance in international message telephone services
An econometric model is estimated to identify determinants of trade imbalance in international message telephone services markets. Results indicate that asymmetric market structure is important in explaining bilateral market imbalances for high income country pairs. For low and high income country pairs, GDP per capita is the dominant cause of traffic imbalances. The findings suggest that telecommunications liberalization policies are effective in reducing distortions in international traffic flows and settlement payments. However, liberalization should be accompanied by developmental programmes that enhance income per capita and telecommunications network investment in developing countries. Such programmes may be effective in providing a more equitable distribution of the gains from telecommunications reform across countries.Trade imbalance; international message telephone services
Secure Vehicular Communication Systems: Implementation, Performance, and Research Challenges
Vehicular Communication (VC) systems are on the verge of practical
deployment. Nonetheless, their security and privacy protection is one of the
problems that have been addressed only recently. In order to show the
feasibility of secure VC, certain implementations are required. In [1] we
discuss the design of a VC security system that has emerged as a result of the
European SeVeCom project. In this second paper, we discuss various issues
related to the implementation and deployment aspects of secure VC systems.
Moreover, we provide an outlook on open security research issues that will
arise as VC systems develop from today's simple prototypes to full-fledged
systems
The Impact of Liberalizing the Telecommunication Sector in Morocco
The purpose of this paper is to present the major developments recorded in telecommunication sector in Morocco and assess the impact of regulating the telecommunication sector in Morocco along the European Union lines. The basic assumption underlying this work is the following. Further liberalization of various market segments of the telecommunication sector would benefit communications intensive industries that provide key âbackbone servicesâ to the economy, such as transport, distribution and finance. It would also improve competitiveness of exporting industries by reducing their costs and facilitating their integration to transnational production networks. The quality and price of telecommunication services directly affect business costs, but also affects the capacity of firms to network and compete in foreign and domestic markets. Finally, development of telecommunication services sector would create more investment opportunities for the domestic private sector, and help attract more FDI and portfolio investment.Telecommunication services, liberalization, Morocco
Analysis of privacy vulnerabilities in single sign-on mechanisms for multimedia websites
This paper studies the privacy risks for the users of two popular single sign-on platforms for web-based content access: OpenID and Facebook Connect. In particular we describe in detail a privacy vulnerability of the OpenID Authentication Protocol that leads to the exposure of the OpenID user identifier to third parties. We illustrate how OpenID agents leak the (potentially unique) OpenID identifiers of their users to third parties, like advertisement and traffic analysis corporations. This vulnerability is a real and widespread privacy risk for OpenID users. This paper also analyzes the privacy of Facebook Connect --the proprietary single sign-on platform that is gaining a lot of popularity recently-- and, we conclude that it is not affected by the same vulnerability but other important privacy issues remain. Finally, this paper studies the solution space of these problems and defines a number of possible countermeasures. In the case of the OpenID vulnerability, we propose three solutions to this problem: one for the long term to avoid the root cause of the vulnerability, and another two short-term mitigations.The work presented in this paper has been funded by the INDECT project (Ref 218086)

Comparative Deregulation of Far Eastern Telecommunications Markets: Economic Incentives and International Competitive Strategies
The deregulation of telecommunications has taken a major step with the WTO agreements in February of
this year. Namely, each of the major Far Eastern countries has agreed to open their market in some form of
planned entry. These markets will allow for the introduction of competition of local and international
services now currently restricted to the local PTT as well as allowing the entry of new services in what are
generally closed markets. This paper analyzes the implications of changes in several key Far Eastern
countries and discusses how this will impact the U.S. economy and the overall policy implications that this
will focus on
International telecommunications market regulation
On 23 February 1999 the Assistant Treasurer referred international telecommunic-ations market regulation for inquiry and report within six months. The report focused on the reform of international telecommunications markets, in particular on the payment arrangements between providers of international telecommunications services.international telecommunications market regulation - pricing - accounting rate system - Internet - Telstra - transmission - technology - cable - public utility
Quantum Key Distribution in OpenSSL
Most of the current communications and systems rely on asymmetric cryptography, which is used to share a unique secret key between two parties communicating, in order to encrypt the information exchanged.
Recently, many researchers state that quantum computing will be a threat in 15-20 years. At the moment there is no quantum computer able to crack classical cryptography, however, a solution to address the threat should be found as soon as possible before classical cryptography reaches its expiration date, and all communications and systems will be cracked.
Quantum cryptography is considered a problem, but from another perspective, it is also the solution to it. In fact, this technology is strong enough to protect both from quantum and classical attacks. Quantum cryptography is considered secure because it is based on quantum physics laws.
The benefits of quantum cryptography, combined with the ones of symmetric cryptography offer an alternative solution to the Key Exchange problem: Quantum Key Distribution (QKD). The technology is a protocol that describes a cryptographic technique to exchange a secret key between two end users/applications within a communication.
This thesis starts by presenting the quantum threat, and the reasons that make quantum computing risky for classical communications and systems. Moreover, it states the importance to invest resources in this field of research in order to find a solution to address the problem once it will be a real risk.
Finally, I explain my contribution to Cefriel activities in the context of Quantum Key Distribution. The internship activity described is a demonstrative approach to integrate QKD technology into the OpenSSL library. The project aims to demonstrate the effectiveness and the feasibility of using QKD technology in SSL communications
