Abstract. We present a non-interactive chosen ciphertext secure threshold encryption system. The proof of security is set in the standard model and does not use random oracles. Our...
This paper proves "tight security in the random-oracle model relative to factorization" for the lowest-cost signature systems available today: every hash-generic signatur...
Often, increased security comes at the expense of user convenience, performance, or compatibility with other systems. The right level of security depends on specific site and use...
We propose and consider a secure printing system for the distributed printing of documents and images over the World Wide Web. This system enables secure sharing, commerce, and co...

Abstract. We consider compositional properties of reactive systems that are secure in a cryptographic sense. We follow the well-known simulatability approach of modern cryptography...
