Authentication is a security service that consists of verifying that someone’s identity is as claimed. There are a number of challenges to presenting information from the authentication process to the user in a way that is meaningful and ensures security. We show examples where authentication requirements are not met, due to user behaviour and properties of existing user interfaces, and suggest...

The effects of the Covid-19 pandemic process on sectoral distribution card payment transactions made over internet in country were analyzed with variance decomposition model, and differences between pre-Covid (June 2019 - March 2020) period post-Covid (April 2020 January 2022) revealed. sectors highest increase domestic use (transaction amount) cards (in terms their share total usage) electrica...

Diagnosis is the task of explaining abnormal behaviors of systems like telecommunication, transportation or energy systems. Given a sequence of observations the problem is to determine, online, all faults that are in line with these observations. Many approaches tackle this problem but they either require domain expertise or a formal description of how observations and faults are connected. Thi...

Regular degree-three Spider-Web networks, SW(m,n), are optimally, scalability prototyped along transportation paths as dual-surveillance − preventing information occlusion, or reliable identity based telecommunication networks. To promote network information transmission such as coping with radio interference and multipath effects, offering dynamic authentication / authorization the performance...

Currently, there is a great need in communities, such as telecommunication network simulation and transportation systems simulation, to be able to publish/pull models to/off the Web and assemble and simulate a virtual configuration of choice by the end-user. For example, in Internet simulations, users would like to be able to search for the most efficient/relevant traffic source models, network...

Optimization models for multi-server queueing systems are very appropriate capacity planning and design tools for manufacturing, telecommunication, transportation, and facility modelling applications. A design methodology based on a two-moment approximation algorithm is utilized for optimizing the number of servers, arrival and service rates, and amount of waiting room in these M/G/c/K multi-se...

Developed countries rely on many infrastructures as energy transportation, water supply, telecommunication, etc., which are more and more mutually dependent. This phenomenon represents a new and very dangerous vulnerability: an accidental or malicious (e.g., terroristic attack) fault could spread across, amplifying its negative consequences. This imposes to develop methodologies and tools to su...

Security is an increasingly important issue for networked services. However, since networked environments may exhibit varying networking behavior and contain heterogeneous devices with varying resources tunable security services are needed. A tunable security service is a service that provides different security configurations that are selected, and possibly altered, at run-time. In this paper,...

Mobile information community develops quickly, as mobile telecommunication technology matches to the third generation. XML-based GIS becomes a global standard and the foundation. Recent developed Geography Markup Language (GML) allows integration of GIS location-based services, telematics, and intelligent transportation systems. In this paper, we propose a tourism information system for support...
