Cybersecurity: All-Hash Message Authentication Code (AH-MAC)

Confidentiality and authenticity of messages are crucial cybersecurity requirements in data exchange. Strong encryption algorithms for message confidentiality are not enough to convey the actual message. A suitable Message Authentication Code (MAC) ensures the authenticity of the message from the sender. The All-Hash Message Authentication Code (AH-MAC) provides a stronger algorithm by enhancing the Hash-Based Message Authentication Code (HMAC) algorithm to stand firm against attacks like Message Extension Attacks.
