A Detailed Dive into Message Authentication Codes (MACs)

Lucia31 Aug, 2025Technology

With the ever-changing digital landscape and a commitment to data protection, Message Authentication Codes (MACs) have developed into critical elements for supporting message integrity and authenticity. We are threatened with an array of cyberattacks, including spoofing, data tampering, and more, all of which highlight the need to know that exposure on a public interface does not change the information shared. This is where MACs are important. The IBM Ponemon Report 2025 emphasizes the escalating costs and complexities of data breaches, demanding a proactive and adaptive approach to cybersecurity. The sharp increase demonstrates the need for authentication mechanisms, like MACs, to help limit trust and risk and reduce operational impact.
