We explore the security of blind signatures under aborts where the user or the signer may stop the interactive signature issue protocol prematurely. Several works on blind signatur...
We investigate the question of what languages can be decided efficiently with the help of a recursive collisionfinding oracle. Such an oracle can be used to break collisionresistan...
Abstract. Let A and B denote cryptographic primitives. A (k, m)robust A-to-B combiner is a construction, which takes m implementations of primitive A as input, and yields an implem...
We extend Goldberg’s multi-server information-theoretic private information retrieval (PIR) with a suite of protocols for privacypreserving e-commerce. Our first protocol adds ...
