中文摘要: 认证加密方案同时提供保密性和完整性两大安全功能,具有极其广泛的应用前景,国际上已经制定了各类相关标准,但是这类标准在我国的国家标准中仍然空缺。我们将在认证加密方案的基本模块、基本概念和基本结构等方面研究的基础上,分析已有认证加密方案在实际应用中的安全性,同时在生日攻击和旁路攻击两个视角下,探求更有效的设计方法和分析方法,建立合适的旁路攻击安全模型,并提出具体的方案设计。并且,我们将提炼出认证加密的安全指标,直接进行方案的设计。通过本项目的研究,我们旨在提出若干分析和设计的创新方法,设计出若干高效率、高安全的,适用于各种应用环境的认证加密方案。力争取得一批有国际影响力的研究成果,为我国认证加密方案标准的制定提供参考。

英文摘要: Authenticated encryption schemes, which provide both privacy and integrity, have wide range of applications. These schemes have been developed into a variety of relevant standards around the world, but such standards in our country are still vacant. We will study the basic modes, definitions and structures, and analyze the security of authenticated encryption schemes in practical applications. In the perspective of birthday attack and side channel attack, we explore more efficient methods of analysis and design, set up a proper security model of side-channel-attack, and propose specific designs. Furthermore we will construct an authenticated encryption scheme directly, based on the analysis of the security indicators. Through this project, we aim to give some innovative methods of analysis and design, more efficient and secure schemes fitting for various application environments. We endeavor to get some internationally influential research results, and provide some references for the national standardization of authenticated encryption schemes.
