Password-based authentication. Authentication is an absolutely essential element of a typical security model. In order for a user to confirm their identity, the individual must provide a piece of information that only the user and the server knows. Hash map is an array of buckets that contain specific AMP #. Three different authentication methods can be used with IKE key determination: Public key encryption, symmetric key encryption, and _____ . MAC algorithm is a symmetric key cryptographic technique to provide message authentication. 04 (c) Describe Elgamal digital signature. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. Answer n this threat, the user is not sure about the originator of the message. As with any MAC, it may be used to simultaneously verify both the data integrity and authenticity of a message. For establishing MAC process, the sender and receiver share a symmetric key K. Essentially, a MAC is an encrypted checksum generated on the underlying message that is sent along with a message to ensure message . 3.1 List three approaches to message authentication. 2 What is a message authentication code?
