WS-SecureConversation is a Web Services specification, created by IBM and others, that works in conjunction with WS-Security, WS-Trust and WS-Policy to allow the creation and sharing of security contexts. Extending the use cases of WS-Security, the purpose of WS-SecureConversation is to establish security contexts for multiple SOAP message exchanges, reducing the overhead of key establishment.〔http://www.ibm.com/developerworks/webservices/library/specification/ws-secon/ Web Services Secure Conversation Language〕 == Features == * Establish a new security context in following modes: * * Security context token created by a security token service (WS-Trust STS) * * Security context token created by one of the communicating parties and propagated with a message * * Security context token created through negotiation/exchanges * Renew security context * Amend Security context (add claims) * Cancel security context * Derive key: parties may use different keys per side and function (sign/encrypt), and change keys frequently to prevent cryptographic attacks * Maintain high secure context WS-SecureConversation is meant to provide an extensible framework and a flexible syntax, with which one could implement various security mechanisms. It does not by itself guarantee security, but the implementor has to ensure that the result is not vulnerable to any attack. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WS-SecureConversation」の詳細全文を読む スポンサード リンク
