    MessageSecurityVersion.
    WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10);

abe.SetKeyDerivation(false);

Dim abe As AsymmetricSecurityBindingElement = CType(SecurityBindingElement.CreateMutualCertificateBindingElement(MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10), AsymmetricSecurityBindingElement)

abe.SetKeyDerivation(False)

Remarks

A derived key is created from an existing key and makes it possible to vary the key used in the course of a conversation. This makes it more difficult for a hacker to decrypt the communication.
