name: ECDSA
full_form: Elliptic Curve DSA
context: DSA and ECDSA private/public key pairs are generated with respect to a particular set of domain parameters. NIST [10] states that although domain parameters may be common to a group of users and may be public information, they shall be managed so that the correct correspondence between a given key pair and its set of domain parameters is maintained for all parties that use the key pair. A set of domain parameters may remain fixed for an extended time period. The goal of this clause is to estimate the minimum number of bits needed to transfer domain parameters. ECDSA uses significantly smaller public key sizes compared to DSA. ECDSA is defined for two arithmetic fields: prime and binary field (representations). In the following only details of ECDSA domain parameters are investigated. NOTE 1: Similar calculations could be done for DSA and ECDSA over binary fields Domain parameters for ECDSA in the general case (see [10], clause 6.1)) are of the form (q, FR, a, b {,
description: Elliptic Curve Digital Signature Algorithm (ECDSA) is a cryptographic technique used to generate and verify digital signatures. It leverages elliptic curve cryptography to ensure the authenticity and integrity of digital communications.
explanation: ECDSA is explicitly described as a cryptographic algorithm used for generating and verifying digital signatures, placing it firmly within the realm of cryptography.
