WebJan 24, 2024 · I was wondering if there is a formula to calculate how long it would take to "guess" a "X-Digit" OTP, presuming you limited the number of times you can try for each code and the number of codes you can get over a period of time. For example: I have a 6-digit code; I can try to verify the code 3 times before it becomes invalid WebThere exists a probabilistic polynomial time (PPT) sampling algorithm Gen s.t. Gen (1 n) = ( k, tk) with k ∈ K ∩ {0, 1} n and tk ∈ {0, 1} * satisfies tk < p ( n ), in which p is some polynomial. Each tk is called the trapdoor corresponding to k. Each trapdoor can be efficiently sampled.
