  4.13 OPC UA security related Services
  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 ... securing all further Message s. Furthermore, all other service Message s are secured with Symmetric Encryption and Symmetric Signature s instead of the asymmetric equivalents. The Server sends its secret
