g A Message Digest is a cryptographic hash function containing a string of digits created by a one-way hashing formula. Message digests are designed to protect the integrity of a piece of data or media to detect changes and alterations to any part of a message. Some examples of message digest are MD2, MD4 and MD5. [Points 4] Assume Alice and Bob share a common secret key E. Describe how Alice can authenticate herself to Bob by sending him one message using Symmetric Encryption. [Points 5] Assume Alice and Bob share a common secret key E. Describe how Alice can authenticate herself to Bob by sending him one message using Message Digest. [Points 5] Assume Alice has pair of public/private keys and her public key is known to Bob. Describe how Alice can authenticate herself to Bob by sending him one message using Asymmetric Encryption.
