ECDSA
Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve variant of the Digital Signature Algorithm (DSA) used for key agreements and digital signature encryption.
The Elliptic Curve Digital Signature Algorithm (ECDSA) utilizes elliptic curve structures (ECC) to provide higher efficiency and robust security over digital signing algorithms. Keys generated using ECDSA are smaller than the Digital Signature Algorithm (DSA) while providing equivalent encryption.
