• Fake VIP Attacks and Their Mitigation via Double-Blind Reputation

  Publication

  • J. Konorski

  - Year 2017

  In a generic setting subsuming communication networks, resource sharing systems, and multi-agent communities, a client generates objects of various classes carrying class-dependent signatures, to which a server assigns class-dependent service quality. A Fake VIP attack consists in false declaration of a high class, with an awareness that detection of object signature at the server side is costly and so invoked reluctantly. We show...

  - Year 2009

  Coraz większa popularność protokołu SIP (Session Initiation Protocol) pociąga za sobą konieczność wymiarowania zasobów sieciowych i badania wydajności samego protokołu z uwagi na potrzebę gwarancji poziomu i jakości usług. Dla realizacji tego celu prowadzi się szereg prac badawczych i niniejsza publikacja jest zreferowaniem wyników takich prac badawczych wykonanych przez autorów. Dotyczą one modelu analitycznego dla opisu poziomu...

  Conformity and conformity testing have always had a crucial role in telecommunications. These issues are especially important in VoIP technology with SIP protocol as there are many hardware, software and service implementations. In this paper a methodology of automatic conformity testing of VoIP connections scenarios applying to any IP network is proposed. Example implementation of the methodology as Linux shell scripts is presented....

  - Zeszyty Naukowe Wydziału ETI Politechniki Gdańskiej. Technologie Informacyjne - Year 2010

  Although Grade of Service is very important in VoIP providers evaluation, We wasn't able to find any paper regarding the topic of measuring GoS variables for IP networks utilizing SIP, which are defined like for PSTN/ISDN/GSM networks (post-selection delay, answering delay, release delay, or probability of end-to-end blocking). Due to the lack of research in this field, it was necessary to start from defining measures and cover...
