Definition. Kerckhoffs’ Principle states that the security of a cryptosystem must lie in the choice of its keys only; everything else (including the algorithm itself) should be considered public knowledge.

Is the Holographic Principle true of quantum field theory?

(If the holographic principle is correct, then physical systems with finite surface area have a finite maximum entropy; but regardless of the truth of the holographic principle, quantum field theory dictates that the entropy of systems with finite radius and energy is finite due to the Bekenstein bound .)

Bruce Schneier ties it in with a belief that all security systems must be designed to fail as gracefully as possible: principle applies beyond codes and ciphers to security systems in general: every secret creates a potential failure point.
