Communication Security

  1. measures that implement and assure security services in a communication system, particularly those that provide data confidentiality and data integrity and that authenticate communicating entities.
  2. state that is reached by applying security services, in particular, state of data confidentiality, integrity, and successfully authenticated communications entities [11].
  • NOTE: This phrase is usually understood to include cryptographic algorithms and key management methods and processes, devices that implement them, and the life-cycle management of keying material and devices. However, cryptographic algorithms and key management methods and processes may not be applicable to some control system applications.
