This chapter provides an understanding of the fundamental principles behind key management. We consider the typical stages in the lifecycle of a cryptographic key and then review each of these stages in some detail. We discuss the choosing of key lengths and look at different techniques for key generation, including key derivation and generation from components. We then look at different techniques for key establishment, including the use of key hierarchies, key wrapping, and quantum key establishment. We then look at key storage and discuss the role of hardware security modules. We also consider key separation, key change, and key destruction, before closing with a short discussion on governance of key management.

E-voting increasingly gains interest in e-Democracy and e-Government movements. Not only the technical security issues of electronic voting systems are of paramount importance, but also the necessity of following an all-embracing approach is challenging and needs to be addressed. This paper discusses e-voting as being a supreme discipline of e-Government. It introduces an innovative e-voting concept using the Internet as the voting channel. The concept introduced is based on Austrian e-Government elements and the Austrian identity management concept in particular. This paper presents a novel approach of building an e-voting system relying on two core principles: strong end-to-end encryption and stringent identity domain separation.

The main aim of this paper is to present the concept of fault-injection backdoors in Random Number Generators. Backdoors can be activated by fault-injection techniques. Presented algorithms can be used in embedded systems like smart-cards and hardware security modules in order to implement subliminal channels in random number generators.

Productive Time

Positioning of the equipment of a manufacturing company is done foreseeing that it will remain fixed for a long time. This is because changes in the plant layout are thought to be costly, as they involve redesigning equipment support services, developing new foundations, using heavy machinery to move equipment, and causing non-productive time at the plant. However, the increased competition due to globalization, lead us to consider the alternative of making modifications to the layout more frequently to improve productivity. Changing the position of the equipment can be facilitated by specifying smaller mobile process equipment or by anticipating the availability of services at different points in the workshop and the existence of cranes or other means of transportation. These forecasts, logically, result in a greater investment in elements that, at least initially, do not generate any profit. This work shows the evaluation of the feasibility of modifying the positions of the equipment when there are variations in the probability distribution in production speeds. This evaluation is carried out using decision trees and process simulation. The case study addressed consists of a generic production line with serial workstations. Jobs arrive at the first computer and join their product on hold if space is available, otherwise the job is lost. In the same way, the product on hold of the other teams are limited in size, and when a product on hold is full, the team behind stops until there is space available. Due to the use, the speeds of the equipment are changing with respect to the ones they had when new: the process times are increasing and / or becoming more variable. To improve productivity under the new process speeds, the space between the equipment can be modified, however, during this change, production must be suspended. This work shows how, by simulating processes and decision trees, it is possible to determine the ranges of values ​​of the suspension time and the cost of transport for which it is convenient to make changes in the spacing of the equipment.
