Data security is an integral part of web based business applications like insurance, banking etc. These applications require a secure infrastructure to meet the security requirements of confidentiality, endpoint authentication, message integrity and no repudiation. Document encryption/decryption and signatures/validation are the data security standards that define XML vocabularies and processing rules to meet these security requirements. In this paper, the authors present a how a file securely passes from sender (server) to the receiver (client) through a central gateway with web services applications which mean a secure architecture for the exchange of confidential documents.
