Divide, Compress and Conquer: Querying XML via Partitioned Path-Based Compressed Data Blocks
We propose a novel Partition Path-Based (PPB) grouping strategy to store compressed XML data in a stream of blocks. In addition, we employ a minimal indexing scheme called Block S...

Security of Signed ElGamal Encryption
Assuming a cryptographically strong cyclic group G of prime order q and a random hash function H, we show that ElGamal encryption with an added Schnorr signature is secure against ...

Stronger Security of Authenticated Key Exchange
In this paper we study security definitions for authenticated key exchange (AKE) protocols. We observe that there are several families of attacks on AKE protocols that lie outsid...

Nearly One-Sided Tests and the Goldreich-Levin Predicate
Abstract. We study statistical tests with binary output that rarely outputs one, which we call nearly one-sided statistical tests. We provide an efficient reduction establishing im...
