  4.13 OPC UA security related Services
  defined in TLS ) is applied by the communication participants. Once established, a SecureChannel uses Symmetric Cryptography keys to encrypt and sign all Messages. Symmetric Cryptography requires a shared key. Asymmetric ... Cryptography is used to create this shared key. The OPC UA Client retrieves the security policies and Certificate s of the OPC UA Server by the previously mentioned discovery services
