We develop a flexible information-flow type system for a range of encryption primitives, precisely reflecting their diverse functional and security features. Our rules enable e...
Security is a critical issue in dynamic and open distributed environments such as network-based services or wireless networks. To ensure that a certain level of security is maintai...
Historically, various different notions of trust can be found, each addressing particular aspects of ICT systems, e.g. trust in electronic commerce systems based on reputation and...
Information flow type systems provide an elegant means to enforce confidentiality of programs. Using the proof assistant Isabelle/HOL, we have specified an information flow ty...
We present a single-database private information retrieval (PIR) scheme with communication complexity O(k+d), where k ≥ log n is a security parameter that depends on the database...
