Research and Design of Secure Data Exchange Model Based on the Interactivity Environment of Energy Internet

With the development of Energy Internet technology, the contents of the external information network are more and more abundant. The data of various types of business systems is frequently interactive between intranet and external information network, but it also brings about lots of security risks. Aiming at the existing security problems, this paper presents a secure data exchange model based on proxy middleware, and the proxy middleware for the client and service is designed in detail. The methods for security filtering are mainly by SOAP digital signature, SOAP encryption, authentication, timestamp, sequence number tag, blacklist and white list, access control for methods, access control for time and so on. The aim is to achieve data encryption and data filtering for data exchange system and guarantee effectively the security of the data exchange system.
