3/31/2023 0 Comments Security through obscurity meaning![]() ![]() Is the assumption that all feasible algorithms will eventually be discovered and implemented really different from the assumption that everything that is computable will eventually be computed? The present paper explores some ways to refine the current models of the attacker, and of the defender, by taking into account their limited logical and programming powers. So the Diffie-Hellman step from unlimited to limited computational powers has not been extended into a step from unlimited to limited logical or programming powers. ![]() The attacker is not viewed as an omnipotent computer any more, but he is still construed as an omnipotent programmer. In fact, modern cryptography goes even further than Shannon or Kerckhoffs in tacitly assuming that *if there is an algorithm that can break the system, then the attacker will surely find that algorithm*. ![]() The popular formulation, going back to Kerckhoffs, is that "there is no security by obscurity", meaning that the algorithms cannot be kept obscured from the attacker, and that security should only rely upon the secret keys. This view is still endorsed in cryptography. Shannon also sought security against the attacker with unlimited logical and observational powers, expressed through the maxim that "the enemy knows the system". Some administrators advocate security through obscurity, aiming to keep as. This idea became one of the greatest new paradigms in computer science, and led to modern cryptography. RC4 is a stream cipher, meaning it acts on a stream of data rather than. (Most people believe that security through obscurity will serve as a functional. Diffie and Hellman refined Shannon's attacker model by taking into account the fact that the real attackers are computationally limited. more focused, clear, and workable definition of online obscurity. This article has been rated as C-Class by WikiProject Vital Articles.Shannon sought security against the attacker with unlimited computational powers: *if an information source conveys some information, then Shannon's attacker will surely extract that information*. Security through obscurity has been listed as a level-5 vital article in Technology. This article has not yet received a rating on the project's importance scale. This article has been rated as C-Class on the project's quality scale. The operating system I run is open source and anyone can get an exact copy of it, but not anyone can log into my system because the key, not the implementation, is secret.
