In context  to my previous mail let me know if this helps.

If I have a policy like shown below , I  would like to know how the 
message is secured. How are the keys derived.

<sp:AsymmetricBinding xmlns:sp="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy">
    <wsp:Policy>
        <sp:InitiatorToken>
            <wsp:Policy>
                <sp:X509Token sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/AlwaysToRecipient">
                    <wsp:Policy>
                        <sp:WssX509V3Token10 />
                        <sp:RequireDerivedKeys/>
                    </wsp:Policy>
                </sp:X509Token>
            </wsp:Policy>
        </sp:InitiatorToken>

        <sp:RecipientToken>
            <wsp:Policy>
                <sp:X509Token sp:IncludeToken="http://schemas.xmlsoap.org/ws/2005/07/securitypolicy/IncludeToken/Never">
                    <wsp:Policy>
                        <sp:WssX509V3Token10 />
                        <sp:RequireDerivedKeys/>
                    </wsp:Policy>
                </sp:X509Token>
            </wsp:Policy>
        </sp:RecipientToken>

        <sp:AlgorithmSuite>
            <wsp:Policy>
                <sp:Basic256 />
            </wsp:Policy>
        </sp:AlgorithmSuite>

        <sp:Layout>

                <sp:Lax />
            </wsp:Policy>
        </sp:Layout>

        <sp:IncludeTimestamp />

        <sp:OnlySignEntireHeadersAndBody />
    </wsp:Policy>
</sp:AsymmetricBinding>

Thank You,
