“I need to learn more about elliptic-curve digital signature algorithms.”

“‘ECDSA’ stand for ‘Elliptic Curve Digital Signature Algorithm.'”

ECDSA involves the use of private keys, public keys and signatures.”

Definition(s) from the Web

  1. Elliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners. Source
  2. As with elliptic-curve cryptography in general, the bit size of the public 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 280 operations to find the private key) the size of an ECDSA private key would be 160 bits, whereas the size of a DSA private key is at least 1024 bits. On the other hand, the signature size is the same for both DSA and ECDSA: approximately 4t bits, where t is the security level measured in bits, that is, about 320 bits for a security level of 80 bits.
