Abstract
In this paper we examine the notion of plaintext awareness as it applies to hybrid encryption schemes. We apply this theory to the Cramer-Shoup hybrid scheme acting on fixed length messages and deduce that the Cramer-Shoup scheme is plaintext-aware in the standard model. This answers a previously open conjecture of Bellare and Palacio on the existence of fully plaintext-aware encryption schemes.
