我们考虑的问题，构造公钥加密方案是弹性的选择密文和密钥泄漏附加。在本文中，我们提出了一个通用的公钥加密结构，是弹性的这种攻击从任何1-通用哈希证明系统和任何4-明智的独立哈希函数。如论文[6]所示，它们可以用基于标准棘手性假设的有效方案来实例化，例如决策Diffie-Hellman，二次剩余和Pailliers决策复合剩余。
We consider the problem of constructing public-key encryption schemes that are resilient to chosen-ciphertext and key-leakage attach. In this paper, we present a generic construction of public-key encryption that is resilient to this attack from any 1-universal hash proof system and any 4-wise independent hash function. As shown in the paper [6] they can be instantiated with efficient schemes based on standard intractability assumptions such as Decisional Diffie-Hellman, Quadratic Residuosity, and Pailliers Decisional Composite Residuosity.
