What is the difference between a MAC and a digital signature?
A MAC (Message Authentication Code) and a digital signature are both cryptographic techniques used in the field of cybersecurity to ensure the integrity and authenticity of messages. While they serve similar purposes, they differ in terms of the algorithms used, the keys employed, and the level of security they provide. A MAC is a symmetric
What is the purpose of a Message Authentication Code (MAC) in cybersecurity?
A Message Authentication Code (MAC) is a cryptographic technique used in cybersecurity to ensure the integrity and authenticity of a message. It provides a way to verify that a message has not been tampered with during transmission and that it originates from a trusted source. MACs are widely used in various security protocols and applications,
How does AES ensure confidentiality and integrity of sensitive information during data transmission and storage?
The Advanced Encryption Standard (AES) is a widely used block cipher cryptosystem that ensures the confidentiality and integrity of sensitive information during data transmission and storage. AES achieves these goals through its secure design and implementation, which incorporates several key features and techniques. Confidentiality is achieved through AES's use of symmetric encryption, where the same
