The principle holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge.
Concurrent testing. Research [1] and literature [2] on concurrency testing and concurrent testing typically focuses on testing software and systems that use concurrent computing. The purpose is, as with most software testing, to understand the behaviour and performance of a software system that uses concurrent computing, particularly assessing ...

A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject ...
