SOAP Security Extensions Japanese page is not available yet. SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment.
SOAP leaves security considerations open.
Our SOAP Security Extensions will add several security features to the SOAP message exchange model, keeping SOAP transport-independent. Specifically, XML Digital Signature for message authentication, element-wise encryption for confidentiality and attribute certificates for authorization will be featured. Our white paper is here . It is based on the above proposals. Also, we are providing the SOAP Envelope API with which the extension is implemented.
