Computational Independence

Björn Fay

Abstract: We will introduce different notions of independence, especially computational independence (or more precise independence by polynomial-size circuits (PSC)), which is the analog to computational indistinguishability. We will give some first implications and will show that an encryption scheme having PSC independent plaintexts and ciphertexts is equivalent to having indistinguishable encryptions.
