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.

To take advantage of the text arrangement functionality in devices with a keyboard, the component provides the '''insertAscii''' method. When Canvas or GameCanvas is used, the keyPressed method provides the ascii code of the button pressed. For normal keypad phones this is the ascii of the number pressed, for qwerty devices it will be the value of the key pressed. The device changes automatically the character set if the shift or numbers key is pressed and so the ascii received is different and corresponds to the intended key. The backspace character is also received as an ascii code, so it is not necessary to call in explicit way the delete function.

要充分利用键盘在设备里的文字安排功能，这个部份提供'''insertAscii'''方法，当Canvas或GameCanvas使用时，keyPressed方法提供按钮按下的ascii码，对於正常键盘手机来说这是按下数字的ascii，对qwerty设备来说它会是按下键的值，假如shift或数值键被按下该设备会自动改变字元集，所以所收到的ascii是不同的并且对应於所要的键，倒退键字元也会以ascii码来收取，所以没有必要用明确的方式来呼叫删除的函式。
