Title:
Equivalence between semantic security and indistinguishability against chosen ciphertext attacks
Authors: Yodai Watanabe, Junji Shikata, Hideki Imai
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.
