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.

It can control the signal light with its internal project; also the user can modify the project by the control panel. And the outstanding point is that the intelligent traffic signal machine has the function of long-distance stakeout and control. Namely the intelligent traffic signal machine can transmit the real time traffic data to the upper computer and display the data on computer. The upper computer can modify and transmit the traffic data to the signal machine, improving the efficiency of the traffic control. The system realizes the function of communication by the TCP/IP protocol, and the capability is very good in reliability and real time.
