Provable Security is a formal method for proving the security of cryptographic schemes, in which the difficulty of breaking a particular scheme is formally related to that of solving a widely believed computational hard problem. Provable security has already become an important theme of theoretical researches in modern cryptography. This dissertation investigates the provable security of public-key encryptions and hybrid encryptions of asymmetric and symmetric encryptions. This includes the various formal security notions and the constructions can be proved to achieve them. Among the constructions, hybrid encryptions are themselves an important way to obtain public-key encryption schemes with chosen ciphertext security. The main results are as follows:(1) The one-wayness of the trapdoor one-way function in NTRU depends on the randomness of the session key, which is different from previous ones. Based on this observation, a new kind of trapdoor one-way function, trapdoor one-way functions with an auxiliary random variable is proposed.

可证明安全性是一种证明密码学方案安全性的形式化方法，它将密码学方案的安全性归约为公认的计算难题，已成为现代密码学领域中理论工作的主线，本文主要研究公钥加密与单双钥混合加密的可证明安全性，这包括它们的各种形式化安全性定义以及达到这些安全性定义的方案构造，而单双钥混合加密本身也是一种构造选择密文安全公钥加密的重要方法，本文得到的主要结果如下：(1)在研究NTRU公钥加密的特殊性基础上，对于公钥加密的陷门单向函数加密模型进行了扩展，提出了具有辅助陷门单向函数的概念，并将其扩展到多元的情况，讨论了可能的密码学用途。

America is the place in which the road culture originated. It also symbolizes the modernistic implications of Road Movies. The novel On the Road brought about fashion of being against the mainstream norms and the film Easy Rider in the sixties resulted in the spirits of Hippie. All the classic texts of Road Movies seem to be at the important points of the American history. Furthermore, sub-types of Road Movies are developed owing to different economic factors, ideologies and values. With the advancement of Hollywood film industry, Road Movies exist with various topics as well as appearances.

Democratic lawmaking procedure is the only resource of legitimacy in a post- metaphysical time. But there was a struggle between two resource of legitimacy which are human right and popular sovereignty. In resent several decades, the claim advocated by liberalism prevails and insists that human right is prior to popular sovereignty. As a west Marxism, Habermas anxious about how the core idea of radical democracy, legitimate law can only be endowed by its addressers, can be realized in a complex modern society. His effort embodied in his discursive interpretation of popular sovereignty and two-track deliberative democracy.

在后形而上学时代，民主的立法程序是合法性的唯一资源，但人权和人民主权这两种合法化资源在政治思想史上一直相互竞争，在近几十年中，自由主义的主张——人权优先于人民主权一直占有压倒性优势，作为西方马克思主义代表人物的哈贝马斯所关心的问题是，激进民主的核心理想——法律的合法性只能由服从它的公民来赋予——如何才能在复杂而多元的现代社会中继续保持其活力？
