  4.13 OPC UA security related Services
  Certificate is sent unencrypted so that the receiver can use it to verify the Asymmetric Signature . The Server decrypts the Message with its Private Key and verifies the Asymmetric Signature ... other service Message s are secured with Symmetric Encryption and Symmetric Signature s instead of the asymmetric equivalents. The Server sends its secret information in the service response
