Now that we are at the end of the term, we are looking to try to find a more suitable date and time for the presentations. We are trying to find a time sometime in the mid-afternoon, i.e., 1:30 - 2:30 or so and we do not have to restrict ourselves to Thursdays. If everyone can please send Jason Jaskolka an email with a list of times that they can definitely NOT make, then we will try to agree on a new time based on everyones availability. Thank you for your cooperation with this.

Date & Time: Thursday, May 5, 2011       4:30 - 5:30 p.m.

Location: ITB/101A

Speaker: Dr. Ridha Khedri

Title: Algebraic Framework for the Specification and Analysis of Cryptographic-key Distribution

Abstract:
Several organizations generate and store a wide range of information in what is commonly referred to as data stores. To access the information within these data stores, two main architectures are widely adopted. The first architecture gives access to information through a trusted server that enforces established confidentiality policies. The second one allows the information to be public but in its encrypted form. Then through a scheme for distribution of cryptographic keys, each user is provided with the keys needed to decrypt only the part of the information she is authorized to access. The presentation focuses on the specification and analysis of key distribution policies in the latter architecture. An algebraic framework that takes into consideration a new perspective in tackling key-distribution problem is introduced. The use of the proposed framework to analyze key-distribution schemes that are representative of the ones found in the literature is presented. The framework enables the specification and the verification of key-distribution policies. The presentation also points the applicability of the presented algebraic framework to several other applications related to measures ensuring information confidentiality.

The presentation that was rescheduled for Thursday, April 21 has been moved back one week to Thursday, April 28. The presentations that were scheduled on or after this date have be shuffled back a few weeks. See the Presentation Schedule for the most up to date schedule.

The presentation that was scheduled for this week on Thursday, April 14 has been postponed until next week. That is, our next presentation will be Thursday, April 21. See the Presentation Schedule for the most up to date schedule.
