Recently, Wang et al. showed that Das et al.'s dynamic ID-based remote user authentication scheme is vulnerable to an impersonation attack and can not achieve mutual authentication. Consequently, a more efficient and secure dynamic ID-based remote user authentication scheme was proposed and claimed that it was now secure and of practical value. However, in this paper, we will show that Wang et al...
Applications with street navigation have been recently introduced on mobile phone devices. A major part of existing systems use integrated GPS as input for indicating the location. However, these systems often fail or make abrupt shifts in urban environment due to occlusion of satellites. Furthermore, they only give the position of a person and not the object of his attention, which is just as important...
This paper presents a web-application supporting structured decision modelling and analysis. The application allows for decision modelling with respect to different preferences and views, allowing for numerically imprecise and vague background probabilities, values, and criteria weights, which further can be adjusted in an interactive fashion when considering calculated decision outcomes. The web-application...
Multi-Agent Path Planning (MAPP) can be considered the basic building block for implementing a reliable Multi-Agent Systems capable for interacting with real world. MAPP main task is how to get the appropriate path for movable agents where each agent is considered a dynamic obstacle to the others. Planning the exact path for each movable agent in a highly dynamic environment is a difficult task. This...
This paper proposed a personal authentication system using small resources for home use. The following three goals were achieved at the same time by this system: (1) identification of each individual, (2) unique existence of each individual in the specified time and space, and (3) no contradiction in the existence of each individual in view of the space and the time before and after an event. Considering...
Information monitoring is a very essential activity for management, control and decision making in various applications. This paper proposes an intelligent system for monitoring information sources that consists of many adaptive agents cooperate with each other in order to monitor every information item updates at the right time without over loading of system resources. The main key of the presented...
Recently, Khan et al. showed that Wang et al.'s dynamic ID-based remote user authentication scheme is not feasible for real-life implementations such as without preserving anonymity of a user during authentication, user cannot choose the password he/she wants, no provision for revocation of lost or stolen smart card, and can not provide session key agreement. Consequently, an improved version of dynamic...
In this paper, we introduce a new scheme for performing IT Risk Management within organizational domains. It adopts a business process-oriented view which integrates risk assessment, vulnerability assessment and risk mitigation into a quantitative framework. Taking the asset dependencies into account, we map business process values to IT hardware components in a hierarchical fashion and combine it...
