WebAug 26, 2024 · However, ECDSA/EdDSA and DSA differ in that DSA uses a mathematical operation known as modular exponentiation while ECDSA/EdDSA uses elliptic curves. The computational complexity of the discrete log problem allows both classes of algorithms to achieve the same level of security as RSA with significantly smaller keys. ...

As with elliptic-curve cryptography in general, the bit size of the private key believed to be needed for ECDSA is about twice the size of the security level, in bits. For example, at a security level of 80 bits—meaning an attacker requires a maximum of about $${\displaystyle 2^{80}}$$ operations to find the private … See more In cryptography, the Elliptic Curve Digital Signature Algorithm (ECDSA) offers a variant of the Digital Signature Algorithm (DSA) which uses elliptic-curve cryptography.
