ACM XML Security Conference 22 November Fairfax VA

"The ACM Workshop on XML Security will address security problems faced by
users who try to develop XML-based applications, Web services, and security
middleware for XML. It ranges from specific security features, such as
digital signatures and element-wise encryption and access control of XML
documents, to XML-based infrastructure, such as Web services and XML
databases. Since many security features for XML have already been
standardized, experimental evaluations of these standards is one of the
important topics covered by this workshop.  

The XML Security workshop seeks submissions from academia and industry
covering novel research on theoretical and practical aspects of the security
required for XML-based systems. We also encourage submissions from
standardization communities such as W3C and OASIS, particularly from the
technical viewpoint."
