The Research on Key Techniques of Cross-Domain Data Services

With the deepening development of Internet plus and cloud computing, big data technology constantly breakthrough in the field of application, cyber security becomes an important research field which can't be ignored in the information environment nowadays. Besides, with the development of the business, there are more and more demands on safe and effective data sharing among the different networks and heterogeneous systems. This paper researches the key technologies for cross-domain data services and proposes a cross-domain security data sharing technology. The technology combines physical isolation with proxy service dynamic configuration on data security sharing. Through analysis and verification, the proposed approach is able to carry out data fields and services mapping transformation in heterogeneous system, which can achieve safe and effective data sharing.
