Summary: 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 nondividability is introduced independent of attack models, and it is shown to be equivalent to each of the previous two notions. This implies the equivalence between semantic security and indistinguishability under any form of attack.
