Due to their nature, Peer-to-Peer (P2P) systems are subject to a wide range of security issues. In this paper, we focus on a specific security property, called the root authenticit...
In this paper, we introduce a framework for secure two-party (S2P) computations, which we call bureaucratic computing, and we demonstrate its efficiency by designing practical S2P...

Abstract: Beim Ubiquitous Computing sollen unz¨ahlige verschiedene Ger¨ate in spontaner Kooperation Dienste auf intelligente und benutzerfreundliche Weise erbringen. Ein Dienst k...
We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...
Secure outsourcing of computation to an untrusted (cloud) service provider is becoming more and more important. Pure cryptographic solutions based on fully homomorphic and verifia...
