Considering these security problems of data transmission such as some import data is transited without encryption, malicious data might be received from a third part in Apparatus And Equipment Sharing Management Platform of Chinese Academy of Sciences (SAMP), SAMP system may result these threats of data theft and data receive insecurity. To solve these problems, combined with the characteristics of SAMP System and its features of data transmission, the technologies of digital signature and encryption of WS-Security based on the Axis2 Rampart module are applied to the issue of data communication security of SAMP System. Firstly, the Axis2 framework, digital signature, encryption technology and the encryption principle of Axis Rampart module are introduced by this paper briefly. After that, encapsulate the data transmission interface of SAMP System by using a data transmission security solution, which uses a combination of digital signature + password + asymmetric encryption of WS-Security. It implements the signature, authentication, encryption and decryption process of message transmission. Finally, it also tests and analyzes the processing time of the response and CPU usage of data transmission interface in SAMP System. The experiment results show that by using the combination technology of Axis2 Rampart module + digital signature + password + encrypt, it can ensure that the security issue of data transmission of SAMP system has a high security, high scalability and high response speed, meet the demand of practical application, and be widely promoted to other Web Application of Enterprise.
