This filter allows the Enterprise Gateway to act as an XML
encrypting Web Service, where clients can send up
XML blocks to the Enterprise Gateway that are required to be encrypted.
The Enterprise Gateway can then encrypt the XML data, replacing it with
<EncryptedData> blocks in the message. The encrypted content is
then returned to the client.
Similarly, the Enterprise Gateway can act as an XML
decrypting Web Service, where clients can send up
<EncryptedData> blocks to the Enterprise Gateway, which can then decrypt
them and return the plain-text data back to the client.
By deploying the Enterprise Gateway as a centralized encryption/decryption
service, clients distributed throughout an SOA (Services Oriented
Architecture) can abstract out the security layer from their core
business logic. This simplifies the logic of the client applications and
makes the task of managing and configuring the security aspect a lot
simpler since it is centralized.
Furthermore, the Enterprise Gateway's XML and cryptographic acceleration
capabilities ensure that the process of encrypting and decrypting XML
messages - a task that involves some very CPU-intensive operations - is
performed at optimum speed.
