Elliptic Curve Cryptography (ECC) - ECC is a type of encryption that uses discrete logarithms applied to elliptical curves. It is considered stronger per bit than normal discrete logarithms.
Monolithic kernel - A monolithic kernel is a type of operating system kernel that runs as a single static executable and contains all the necessary functionality precompiled in. It runs in supervisor mode, or ring 0, and interfaces between the hardware and the operating system and applications.
Graham-Denning model - The Graham-Denning model is a type of access control model that uses objects, subjects, and rules to define access rights. A subject can execute eight specific rules on an object: transfer access, grant access, delete access, read object, create object, destroy object, create subject, and destroy subject.
