A trapdoor or hatch is a sliding or hinged door that is flush with the surface of a floor, ceiling, or roof. [1] It is traditionally small in size. [2] It was invented to facilitate the hoisting of grain up through mills, however, its list of uses has grown over time. [3]
In mathematical terms, if f is a trapdoor function, then there exists some secret information t, such that given f(x) and t, it is easy to compute x. Consider a padlock and its key. It is trivial to change the padlock from open to closed without using the key, by pushing the shackle into the lock mechanism.
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer"—a tiny computer-within-a-computer such as that found in Intel's AMT technology).
These 15 clever hidden door ideas lead to secret rooms or storage spaces, adding a little mystery to your home. Check out these designer spaces for inspiration.
[24] e is a secret key presumably known only by NSA, and the alleged backdoor is a kleptographic asymmetric hidden backdoor. [39] Matthew Green's blog post The Many Flaws of Dual_EC_DRBG [40] has a simplified explanation of how the alleged NSA backdoor works by employing the discrete-log kleptogram introduced in Crypto 1997.
