| Abstract: | Encryption international standards and popular commercial encryption systems are reviewed. An unsymmetrical security transmission structure based on Advanced Encryption Standard(AES), public key encryption system(RSA) and message digest Hash function(MD5) has been devised by considering of the characteristics of actual management information systems. The hybrid encryption system was implemented by C# language and it was tested in the practical situation. The results show that this system has an effective and integrated structure, by means of which secure storage and secure transmission of information system data can be assured. Moreover, the solution devised allows optimization of the performance of management information systems given sufficient encryption intensity. |
