 Data Authentication Algorithm

A Data Authentication Algorithm is a cryptographic mechanism that ensures the integrity and authenticity of data. It verifies that the data has not been altered or tampered with and confirms the identity of the source sending the data. Data authentication is critical in various applications, including secure communications, digital signatures, and data integrity checks. ### Key Concepts 1. **Integrity**: Ensures that data has not been modified in transit or at rest. The algorithm detects any unauthorized changes to the data.
