5.7.3.1 Description

private key associated with the clientCertificate specified in the CreateSession request. The data to sign is described in 6.1.8 . Once used, a serverNonce cannot be used again. For that reason ... used, then ActivateSession over a new SecureChannel shall fail if the SecureChannel is using Sign . The ActivateSession Service is used to associate a user identity with a Session . When

6.8.1 Secure Channel Handshake

encrypting data with AuthenticatedEncryption is discussed in 6.7.1 . When not using AuthenticatedEncryption with Sign only, the EncryptionKeyLength and InitializationVectorLength are set to 0 in the calculation of L in Step

7.4.1 Overview

None indicates that the Nonces are not signed. The SecurityMode is set to Sign unless the SecurityPolicy is None ; in this case the SecurityMode shall be set to None
