The Research On Policy Of Bank Business Network System's Data Encryption And Certification Authentication

The research on the security policies of Bank business network system plays an important role in promoting new business, especially in Internet banking's business. Although it's a huge project, the most fundamental and critical theme includes two parts, one is the research on data encryption, the other is on certification authentication. Being lack of research and responding measures after data centralization and network opening, the system is susceptible to unauthorized access. However, we aim at devising an encryption solution with feasibility and extensity to meet the demands of security requirements and to realize data transmission encryption and certification authentication simultaneously. Former system is taken as the object in this paper. Based on today's network and its structure, system's security hole is analyzed, then security demanding is suggested. After the introduction of theory, one policy is finally available. To testify its feasibility, the policy is applied in an actual system to analyze encryption keys and encryption key management, its execution steps in applying this policy are also summarized. In a word, this policy can solve the problem of security hole in one aspect, so it's of great significance to perfect system's security.
