DISSERTATION Denial-of-Service and Unsolicited Communication Protection in Global Voice-over-IP Infrastructures
The switch of future telecommunication infrastructures to packet switched communication using the Internet Protocol (IP) raises new issues and challenges regarding security. Telecom operators will likely face challenges similar to the ones encountered in the last years by operators of established IP services like World Wide Web (WWW) or Email. The first part of this thesis presents attack scena...
متن کاملSeamless Multimedia Services Over All-IP Based Infrastructures: The EVOLUTE Approach
The increasing amount of roaming Internet users in combination with the evolution of IP-based applications has created a strong demand for wide-area, broadband access to a number of IP multimedia services. Wireless LANs can complement the next-generation cellular networks, by offering a cost-efficient, wireless broadband data solution for hot spot areas. By combining the wide coverage of next-g...
متن کاملAn Overview of Macro-Mobility Management in Next Generation All-IP Based Wireless Network Infrastructures
Next generation wireless systems are most likely to have an IP based core network. Mobile IP is a proposed standard of the IETF (Internet Engineering Task Force) designed to assist different mobile users. Mobile IP provides an elegant solution for node mobility when the mobile node infrequently moves. However, it implies a relatively large overhead and delay, due to indirect communications. In ...

متن کاملGroups from cyclic infrastructures and Pohlig-Hellman in certain infrastructures
In discrete logarithm based cryptography, a method by Pohlig and Hellman allows solving the discrete logarithm problem efficiently if the group order is known and has no large prime factors. The consequence is that such groups are avoided. In the past, there have been proposals for cryptography based on cyclic infrastructures. We will show that the Pohlig-Hellman method can be adapted to certai...
