Security by obscurity not so bad after all, argues prof. Game theory suggests secrecy has some uses
October 06, 2011
"The Kerckhoffs' Principle holds that withholding information on how a system works is no security defence. A second accepted principle is that a defender has to defend against all possible attack vectors, whereas the attacker only needs to find one overlooked flaw to be successful, the so-called fortification principle.
However a new research paper from Prof Dusko Pavlovic of Royal Holloway, University of London, applies game theory to the conflict between hackers and security defenders in suggesting system security can be improved by making it difficult for attackers to figure out how their mark works. For example, adding a layer of obfuscation to a software application can make it harder to reverse engineer."
