Secure access policy for efficient resource in mobile computing environment

As the Internet was activated and the mobile environment developed, it has become more common to access dynamic XML data regardless of location and time. XML is widely used for information exchange and representation of data for databases, applications, etc., using the advantage to describe information. As a result, large-capacity XML data becomes increasingly complex, and demand for data access policies is increasing. Security issues such as authorization of access to resources, authentication, security enhancement and privacy arise. The mobile computing environment differs from existing information systems in several ways, so it is difficult to apply the existing access control as it is. Therefore, this paper proposes a secure access policy method for query processing to enable efficient resource management in dynamic XML data environment. The results of the evaluation are also presented to show that the additionally proposed method is efficient and excellent.
