这项工作的目的是检验语义安全概念和对选择密文攻击的不可区分性之间的关系。为此，引入了一种新的安全概念，称为不可分红性，它独立于攻击模型，并被证明与前两个概念中的每一个等价。这意味着在任何形式的攻击下语义安全和不可区分之间的等价性。
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 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.
