Weird. The WSDL doesn't have a signature parameter for any type. BUT, I found this in Amazon dev forums. Recommend you to check it out (also, if you develop using amazon services, keep that resource at hand

Looks like security gates for services are now taller and bigger, mate
EDIT: This question link to some example in C#. Maybe it can help you out Amazon (AWS) - The request must contain the parameter Signature
And this is an example in AWS forums with PHP https://forums.aws.amazon.com/message.jspa?messageID=149715
