ECDSA offers a variant of the Digital Signature Algorithm (DSA) which uses elliptic curve cryptography.



The Elliptic Curve Digital Signature Algorithm (ECDSA) is a Digital Signature Algorithm (DSA) that uses keys derived from elliptic curve cryptography (ECC). It is a particularly efficient equation based on public key cryptography (PKC) temuland crypto glossary asymmetric cryptography Asymmetric cryptography is a process that uses a pair of related keys, one public key and one private key, to encrypt and decrypt a message and protect it from unauthorized access or useLearn more.

ECDSA is used across many security systems, is popular for use in secure messaging apps, and it is the basis of BitcoinBitcoin1$ 60,558.230.18%-6.01%-15.89%details security (with Bitcoin “addresses” serving as public keys).

The main feature of ECDSA versus another popular algorithm, RSA, is that ECDSA provides a higher degree of security with shorter key lengths. This increases its ROI further as ECDSA uses less computer power than RSAm a less secure competing equation.

A cryptographic system should be secure even if everything about the system, except the key, is public knowledge.
