Incorporating Dynamic Constraints in the Flexible Authorization Framework,ic constraints are enforced during the policy compilation time, and the dynamic constraints are enforced during run time. While there are several logic-based access control policy frameworks, they have a limited power in expressing and enforcing constraints (especially the dynamic constraints). We p

Better Privacy for Trusted Computing Platforms, indeed a trusted hardware device. In turn, This enables two communication partners to establish that the other end is a secure computing platform and hence it is safe exchange data. Both these remote identification protocols provide some degree of privacy to users of the platforms. That is, the com

A Formalization of Anonymity and Onion Routing,lization of other security goals, such as privacy, has received less attention. Due to the increasing importance of privacy in the current society, formal methods will also become indispensable in this area. Therefore, we propose a formal definition of the notion of anonymity in presence of an obser

Comparison Between Two Practical Mix Designs,f simulations which model the algorithms used by these mixing applications. Our simulations are based on actual traffic data obtained from a public anonymous remailer (mix node). We determine that assumptions made in previous literature about the distribution of mix input traffic are incorrect: in p

Signature Bouquets: Immutability for Aggregated/Condensed Signatures,Since a service provider is almost never fully trusted, security and privacy of outsourced data are important concerns..This paper focuses on integrity and authenticity issues in outsourced databases. Whenever someone queries a hosted database, the returned results must be demonstrably authentic: th
