The Elliptic Curve Digital Signature Algorithm (ECDSA) is a cryptographic algorithm used for digital signatures that relies on the mathematics of elliptic curves. It offers a way to securely verify the authenticity and integrity of a message, while requiring smaller keys compared to other signature algorithms like RSA, making it more efficient. ECDSA is widely used in various security protocols and applications, significantly enhancing the efficiency and security of digital communications.
