Abstract:

With the rapid development of information technology, the information security has gained more and more attention. Especially, the requirement for the data security sharing of heterogeneous systems between different network domains is more and more. Therefore, it is very important to study a reasonable and effective data security sharing measures between different network domains. On this foundation, we propose a flexible configuration technology based on WSDL to realize the cross domain security data sharing. This technology realizes the security sharing of data through the physical unilateral transmission, and proposes the method of dynamic allocation of proxy service. Through analysis and verification, this method can realize the mapping and transformation of the data field of heterogeneous systems, and can realize the flexible configuration of application system service. In a word, it can achieve the purpose of data security and efficient transmission.

Key words: cross domain security, flexible configuration, data sharing, unilateral transmission, physical isolation
