  4.7 Security Profiles
  problem. Each security Profile defines a set of algorithms that work together. They include: Asymmetric Encryption algorithm Asymmetric Signature algorithm Certificate Key algorithm Certificate Signature algorithm Ephemeral Key algorithm ... required for all security Profiles (i.e. Ephemeral Keys are only required for ECC, Asymmetric Encryption is only required for RSA) OPC 10000-7 is the informative specification of the Profiles

  4.13 OPC UA security related Services
  with the OpenSecureChannel service Message to the Server . This Message is secured by applying Asymmetric Encryption with the Server's Public Key and by generating Asymmetric Signatures with the Client ... 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 information in the service response

  5.2.5 Confidentiality
  Confidentiality OPC UA uses Symmetric and Asymmetric Encryption to protect Confidentiality as a security objective . Thereby Asymmetric Encryption is used for key agreement and Symmetric Encryption for securing all other ... relies upon the PKI ( Public Key Infrastructure ) to manage keys used for Asymmetric Encryption which is then used to establish symmetric session keys. The length of the certificate chain

  6.9 Diffie-Hellman Key Agreement (RSA)
  Diffie-Hellman Key Agreement (RSA) The original RSA based profiles used AsymmetricEncryption to negotiate the symmetric keys used for the SecureChannel . Diffie-Hellman Key Agreement (RSA-DH) allows
