Abstract — The Email messages are not secured over the internet as the headers are not authentic. The secured XML email has development a method for establishing a secure e-mail communication channel between sender and recipient. Secured XML Email has the significant advantage that all headers

Web-based applications greatly increase information availability and ease of access, which is optimal for public information. The distribution and sharing by the Web of information that must be accessed in a selective way requires the definition and enforcement of security controls, ensuring

The prevalent use of XML highlights the need for a generic, flexible access-control mechanism for XML documents that supports efficient and secure query access, without revealing sensitive information to unauthorized users. This paper introduces a novel paradigm for specifying XML security

The integration of isolated XML repositories has drawn more and more interest recently. In this paper, we propose XML federations to provide global e-services while preserving the necessary autonomy and security of each individual repository. First we show a logical architecture of XML federations

and effective XML processing has posed a new challenge for the database world. This paper discusses a fast and efficient indexing technique for XML documents, and introduces the XML graph numbering scheme. It can be used for indexing and securing graph structure of XML documents. This technique provides

In this paper, we define a security model [14] for a native XML database which supports the XUpdate language. Our model is inspired by the SQL security model which is the most famous security model for database. We first define a generic access control model for tree data structures. Then, we apply

, we have proposed a methodological approach for the model driven development of secure XML data warehouses.

complex join expressions to several binary structural joins. In this paper, we are proposing a new structural join algorithm called sequence join algorithm, for sequential regular path expressions in securing XML query processing storage. It exploits information about position of the elements in a product

issues around metadata management needs to be addressed in order to build trust and confidence to ambient environments. The aim of this paper is to bring together the worlds of security and XML-formatted metadata management in such a way that, on the one hand the requirement on secure metadata management
