Introducing mobility into a communications environment that was initially designed for fixed nodes brings up many challenges that come from a technical as well as from a security point of view. The challenges posed by introducing mobility for seamlessly roaming between IP networks are addressed by the MobilelP standard. This chapter describes the solution proposed by MobilelP with a focus on the security mechanisms used in version 6 of this protocol.
To achieve the goal of security and privacy in future mobile communication networks, further research and technology development will be required. The roadmap presented in this chapter pioneers the boundaries of mobile privacy and security from a broad perspective. It registers the mobile privacy and security requirements of the actors on whom the success of future mobile communications, systems and services depends, it gives an overview of the current state-of-the-art in mobile security and privacy, addresses non-technical aspects, conducts a SWOT analysis from a European perspective and ultimately identifies the areas where research, standardisation and development will be most needed and beneficial in the coming years, so that we can progress rapidly and efficiently towards a trusted mobile environment.
The paper discusses the practical issues that arise when securing the access to the World Wide Web (WWW). A brief overview of the different protocols that are proposed to secure the WWW is given and the current status of the U.S. export regulations is reviewed. An attack on SSL 2.0 is detailed which exploits some of the weaknesses in this protocol. The setup of a secure server with access control is explained. At the client side, existing solutions to provide export browsers with strong cryptography are evaluated, and the authors also introduce some improvements. Finally, the performance of the secure system is evaluated and compared to that of the regular HTTP connection.
Treatment for rigid mallet toe deformity of the hallux has commonly consisted of arthrodesis of this interphalangeal joint. However, such procedure is not without complications resulting in operative revision. We report on a case of considerable deformity of the distal phalanx of the hallux following hallux interphalangeal joint arthrodesis that underwent revision using a unique crescentic osteotomy technique.
