We propose the first single sign-on system in which a user can access services using unlinkable digital pseudonyms that can all be revoked in case she abuses any one service. Our ...
Abstract. This paper presents a novel use of pairing-based cryptography to improve circuit construction in onion routing anonymity networks. Instead of iteratively and interactivel...
Abstract. A protocol compiler is described, that transforms any provably secure authenticated 2-party key establishment into a provably secure authenticated group key establishment...

Abstract. The hash algorithm forms the basis of many popular cryptographic protocols and it is therefore important to find throughput optimal implementations. Though there have be...
This paper investigates the general problem of performing key-value search at untrusted servers without loss of user privacy. Specifically, given key-value pairs from multiple ow...
