The need for secure signatures makes sense. It was funny to think of someone literally copying and pasting a signature onto a check. With the digital age, it makes sense for an increase of security for signatures.
One thing I was confused about in the RSA method was why did Alice send the message as part of her signature? I thought that was the point of encryption to keep the message secret. Does a hash function not adequately protect signatures or is that only a problem with the primes aren't big enough?
