Open PhD Position

The research group ISSI (Information Systems and Security) at the Department of Computer Science of the University of Dortmund, Germany, offers a PhD position for preparing a dissertation that contributes to an ongoing project on "controlled query evaluation".

Controlled query evaluation aims at providing informative answers to sequences of queries, while preserving the confidentiality of the specific sentences of a security policy, even if the user can take advantage of a priori knowledge, previous answers, and inferences based on that. Appropriate concepts have been introduced by Sicherman et al and Bonatti et al, and further studied and extended by Biskup, Bonatti and Weibert, using a logic-oriented approach to information systems. The specific topic of the dissertation is open to discussion, but should fit the research agenda of the group.

Applicants should have received a qualified university diploma/master degree in computer science or closely relatred sciences. Sufficient background knowledge in the fields "security in computing" and/or "logic in computer science" is appreciated.

Interested students are invited to contact Joachim Biskup for more detailed information and to inspect the web pages of the ISSI group, using the addresses given below. After the selection process, a formal application for a PhD grant must be directed to the DFG-Graduiertenkolleg on "Mathematische und ingenieurwissenschaftliche Methoden fuer sichere Datenuebertragung und Informationsvermittlung"
