Paper: Equivalence between semantic security and indistinguishability against chosen ciphertext attacks

Authors: Yodai Watanabe Junji Shikata Hideki Imai URL: http://eprint.iacr.org/2002/033 Search ePrint Search Google 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.
