Current authentication protocols (i.e. user login and password) successfully restrict access to properly configured workstations and servers. Traditionally, a user’s privileges will allow (or deny) access to files or applications on the local machine or on other machines within its domain.

Receipt-freeness is an essential security property in electronic voting to prevent vote buying, selling or coercion. In this paper, we propose an efficient mixnet-based receipt-free voting scheme by modifying a voting scheme of Lee et al. The receipt-freeness property is obtained through the randomization service given by a trusted administrator, and assuming that two-way untappable channel is ...

In this article the authors examine characterizations of faculty-administrator relationships, in particular as related to shared governance. Two primary perspectives guided the study. The first perspective focused on the fragile nature of shared governance, characterized by a lack of harmony and mistrust. The second perspective focused on the root of faculty-administrator tension as both cultur...

In the Pegasus prototype multidatabase system, the key to the problem of object identity is a differentiation between the view of a data administrator, capturing all the underlying discrepancies and their solutions, and the view of an end user or application, in which only a consistent result is visible. New language constructs with which the administrator can describe solutions to identity pro...

System administrators are users too and there have been few user studies of them in the security domain. This paper describes the challenges we faced in designing and performing studies of security system administrators using visualization tools as well as our experiences in addressing these challenges.

In this paper, dynamic aspects of railway infrastructure operation and maintenance costs in Sweden are explored. Econometric cost functions are estimated to check the robustness of previous marginal cost estimates by introducing lags and leads of both dependent and independent variables. We find support for a forward-looking behaviour within the Swedish National Rail Administration (Banverket) ...
