Cryptography Problem Set #2 Guide by ayush is a document available to read on EtoBox.

This document is a problem set for a cryptography course that is due on March 1, 2005. It contains 4 problems: 1) Analyzing whether 4 functions are one-way based on a given one-way function f. 2) Proving that a GM-secure cryptosystem implies the existence of a one-way function. 3) Proving that 3 definitions of one-bit security for a cryptosystem are equivalent. 4) Proving that no GM-secure public-key cryptosystem can have ciphertexts the same length as plaintexts.
