Annex D (Informative) - Encryption Keys<br />
This standard uses fixed private keys for encryption, to avoid system overhead associated with public keys. Several<br />
recommendations for handling private keys apply:<br />
• during system deployment, knowledge of the keys to be used for an installed group of systems should be limited to as<br />
few personnel as possible<br />
• the design of the equipment should ensure that authorized personnel are able to store (write) keys in premises<br />
equipment or central station receivers, but it should not be possible to read back these keys<br />
• section 5.1 of NIST Special Publication 800-38A provides a useful overview of the cipher block process used by this<br />
standard<br />
