Eve may be able to forge Alice's signature on a message with the content selectively chosen by Eve. Let the signing function is S(M)=P*W*d(mod n), where P, W, d, and n are the number of paragraphs in the message, the number of words in the message, the private key of sender, and a known prime number. Give an example showing how this forgery works. Eve may be able to forge Alice's signature on a message with the content selectively chosen by Eve.
