The thing about CIA is that it is commonly used in security (not cryptography) courses to mean Confidentiality, Integrity (of systems) and Availability (instead of Authentication). Availability of systems, services and information.
For crypto I always talked about CAIN or PAIN (like in no PAIN no gain, or cryptography is allot of PAIN). -- note, I also prefer the word Confidentiality over Privacy, the latter being to high level and I usually reserve it to mean the hiding of who is communicating with who (anonymity systems...). When introducing digital signatures I always state that they provide integrity (as do MACs, which I introduce beforehand) but also the possibility of non-repudiation. And then I go on stating that it is very hard, if not impossible, to in fact implement non-repudiation. --Anton --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
