Markup language security messages are processed. A template corresponding to a markup language security message is identified. The markup language security message is parsed for variable values using the template. A transition sequence is generated that represents the entire markup language security message. Each transition in the transition sequence is associated with a portion of the markup language security message. A lightweight data model of the markup language security message is populated using the transition sequence. The lightweight data model includes nodes for the variable values and a set of selected constant values.

Processing extensible markup language security messages using delta parsing technology

An XML digital signature mechanism for providing message integrity. A sending party serializes a source XML document into a serialized byte array, calculates the source offset and length of the array of the signed part in the serialized byte array, and calculates a source hash value using the serialized array and the source offset and length. The serialized byte array is a non-canonicalized array. The array and source hash value used to sign a part or the whole of the serialized byte array is sent to a receiving party. The receiving party calculates the target offset and length of the signed part in the serialized byte array and calculates a target hash value of the signed part by using the array and the target offset and length. The receiving party compares the target hash value and the source hash value to verify the integrity of the target XML document.

A message gateway apparatus is provided for use in a web service system to process a message containing a request for a destination web service application, in which the message includes a plurality of events within a structured document conforming to a web service protocol and each event of the plurality of events has a name and a content thereof. The message gateway apparatus comprises a message parsing module configured to sequentially identify the events of the plurality of events of the message, an input object creation module configured to sequentially extract the events of the plurality of events from the message parsing module, and a message filtering module configured to sequentially access the events of the plurality of events as the events are extracted from the message parsing module by the input object creation module to analyze the name of each event and perform security processing on the content of each event for which the corresponding name indicates that security measures have been applied according to a security protocol. The input object creation module is configured to construct an input object including input parameters for the destination web service application based on the message. The input object creation module constructing the input object by adding a representation of each event of the plurality of events to the input object after each event is accessed by the message filtering module.
