基于DCR假设的KDM-CCA安全性
KDM-CCA security based on DCR assumption
摘要
Abstract
The definition of KDM(Key-Dependent Message)security is related to some specific ensemble F . By intro-ducing a new ensemble of functions, it proves that, in two user cases, the DCR-based scheme proposed by Cramer and Shoup is KDM-CCA secure w.r.t. the new ensemble. Since the CS-DCR scheme is very efficient, an encryption scheme is gotten which is not only somewhat KDM-CCA secure but also very efficient.关键词
