Problem 3. Prove that any efficient adversary A which can win

Problem 3. Prove that any efficient adversary A which can win the following game with nonnegligible probability can be used to design another adversary B which wins the OWF game for f. 1. C draws (vk,sk)Gen(1n) and sends vk to A. 2. A sends msg {0,1} to C. 3. C sends to A where =Sign(msg, sk). 4. A sends (msg,) to C and wins if msg=msg{0,1} and Verify (msg,,vk)=1
