Equivalence between semantic security and indistinguishability against chosen ciphertext attacks
Abstract
The aim of this work is to examine the relation between the notions of semantic security and indistinguishability against chosen ciphertext attacks. For this purpose, a new security notion called non-dividability is introduced independent of attack models, and is shown to be equivalent to both of the two notions. This result is expected to provide a clearer understanding of the equivalence between semantic security and indistinguishability under any form of attack.
