Pipelines, wellbores and ground installations are permanently controlled by sensorsspread across the crucial points in the whole area. One of the most popular techniques to supportproper oil drive in a wellbore is a Gas Lift. In this paper we present the concept of using wireless sensornetwork (WSN) in the oil and gas industry installations. Assuming that Gas Lift Valves (GLVs) ina wellbore annulus...
The security modelling of IT systems is a very complicated task. One of the issues which must be analysed is the performance of IT systems. In many cases the guaranteed security level is too high in relation to the real threats. The overestimation of security measures can decrease system performance. The paper presents the analysis of Kerberos cryptographic protocol in terms of quality of protection...
