The research password changes objective law, applies in the establishment password by the conservative correspondence secret, is called the code study; Applies gains the communication intelligence in code-breaking, is called breaks the code study, general name cryptology. The cryptology is in the code with breaks the code the struggle practices develops gradually, and along with the advanced sciences and technologys application, has become a comprehensive most advanced technique science。It with the linguistics, mathematics, electronics, acoustics, the information theory, the computer science and so on has widespread and close contacting. Its reality research results, especially various countries government presently uses the password establishes and breaks the method to have the high confidentiality. Along with the information and information technologys development, the electron data exchange becomes the main form which gradually the people exchange, the information security in the exchange status is getting more and more important. This thesis study on the cryptology basic concept, introduced the cryptology history separately, the contempt encryption. This article key point is conducting the research to the cryptology domestic and foreign research level. It makes the introduction after the domestic and foreign research levels survey carried on the statistics through web of science taking “cryptography” as the topic to the literature material. It Obtains the cryptology research overall tendency from q
