Second, we observe that if the oracle o of d′ is the function f described in the exercise then, for all k, we have that pr(d′fk(·)(1n) = 1) = 1 because k ∨ 1n is always equal to 1n. Students are asked to implement solutions to the exercises in a programming language of their choice and include estimates and times for completion. Homework exercises from the "understanding cryptography" textbook and accompanying lecture series. The gronsfeld cipher is a modern variant of the vigen`ere cipher in which a key number is used instead of a keyword, e.g. 14965. other ciphers in the next exercises and in the bibliography, including the polybius cipher, the playfair cipher, the adfgvx cipher, and the enigma machine.
