Acronyms and Terms

The following acronyms and terms apply to a secure JUNOS software environment and are not necessarily Common Criteria-specific.

EAL—Evaluation Assurance Level. An assurance requirement defined by Common Criteria. For example, EAL2 is Evaluation Assurance Level 2 and EAL3 is Evaluation Assurance Level 3. Higher levels have more stringent requirements.
ECC—Elliptical Curve Cryptography. A public key algorithm technique applied over an elliptical curve (a mathematical expression). Operations over an elliptical curve are known to be faster, more secure, and provide equivalent security using a smaller number of bits.
ECDH—Elliptical Curve Diffie-Hellman. Applies the Diffie-Hellman algorithm over an elliptical curve.
ECDSA—Elliptical curve digital signature algorithm. Applies digital signatures over an elliptical curve.
FIPS—Federal Information Processing Standard. FIPS-140-2 and FIPS 140-3 deal with security and cryptographic modules.
KATS—Known Answer Test System. Used to validate the cryptographic algorithm implementation, typically for verifying FIPS compliance.
TOE—Target of Evaluation. Used to identify the component under evaluation for compliance.
