Abstract. We provide the first proof of security for Abreast-DM, one of the oldest and most wellknown constructions for turning a block cipher with n-bit block length and 2n-bit k...

Abstract. We propose a simple and efficient construction of a CCAsecure public-key encryption scheme from any CPA-secure identity-based encryption (IBE) scheme. Our construction re...
