Modular design is a common approach for dealing with complex tasks in modern cryptology; in which the main problem is that the secure sub-protocols no longer remain their security in the hybrid protocol. Canetti presents universally composable security framework for designing secure hybrid protocol.

协议模块化设计是协议设计领域的重要研究方向，其中最大的困难是子协议的安全性并不能保证组合协议的安全性。

In this paper we firstly discuss the general concepts of compter security and cryptology, and then describe the mostly used modern encryption methods and technologies. We detail the advantages and disadvantages of symmetric algorithm, public-key algorithm and one-way hash function. At last we put forward a new block cipher - permutation code, and describe the secret hash digital signature and online electronic contracting with the trusted third party system.
