NIST IR 7298 Revision 1, Glossary of Key Information Security Terms
Enclave – Collection of information systems connected by one or more internal
networks under the control of a single authority and security policy.
The systems may be structured by physical proximity or by function,
independent of location.
SOURCE: CNSSI-4009
Enclave Boundary – Point at which an enclave’s internal network service layer connects to
an external network’s service layer, i.e., to another enclave or to a
Wide Area Network (WAN).

Encode – Convert plain text to cipher text by means of a code.
SOURCE: CNSSI-4009
Encrypt – Generic term encompassing encipher and encode.
SOURCE: CNSSI-4009
Encrypted Key – A cryptographic key that has been encrypted using an Approved
security function with a key encrypting key, a PIN, or a password in
order to disguise the value of the underlying plaintext key.
SOURCE: FIPS 140-2
Encrypted Network – A network on which messages are encrypted (e.g., using DES, AES,
or other appropriate algorithms) to prevent reading by unauthorized
parties.
SOURCE: SP 800-32
Encryption – Conversion of plaintext to ciphertext through the use of a
cryptographic algorithm.
SOURCE: FIPS 185
Encryption – The process of changing plaintext into ciphertext for the purpose of
security or privacy.
SOURCE: SP 800-21; CNSSI-4009
Encryption Algorithm – Set of mathematically expressed rules for rendering data
unintelligible by executing a series of conversions controlled by a
key.
SOURCE: CNSSI-4009
Encryption Certificate – A certificate containing a public key that is used to encrypt electronic
messages, files, documents, or data transmissions, or to establish or
exchange a session key for these same purposes.
