Hash Functions and Authentication Codes Paper Research the following topic: When looking at message authentication three alternative functions are used message encryption, message authentication code (MAC) and hash function. Discuss some of the classical applications of hash functions. What characteristics are needed in a secure hash function? What is the role of a compression function in a hash function? Explain the difference between message authentication code and a one-way hash function. Indicate what ways a hash value can be secured so as to provide message authentication. How is a digital signature similar to a MAC? Does a hash then sign make RSA signature secure against all chosen message attacks? Prepare a 350- to 1,050-word paper that fully discusses the topic questions
