ECDSA

(Elliptic Curve Digital Signature Algorithm) A digital signature that is derived using elliptic curve cryptography. A variation of the DSA standard, ECDSA is the cryptographic method used to generate a public key from a private key as well as the digital signature in spendable Bitcoin records known as a "unspent transaction outputs" (UTXOs).

The public key is used to verify that the message, be it a Bitcoin transaction or any other data, was created by the holder of the private key. See elliptic curve cryptography and digital signature.

(2) Different from general Elliptic Curve Digital Signature Algorithm (ECDSA), the key is a point on elliptic curves rather than a scalar in scalar multiplication for SM9 algorithm.
We also include ECDSA in the comparison as a criterion [24], which is the signature algorithm adopted in [11].
RSA [24] and ECDSA [25] are two well-known public key cryptography techniques that use two keys; private and public.
We consider that each AP has a signing/verification key pair (pk, sk) of a common digital signature scheme ECDSA [23].
(9) Elliptic curve digital signature algorithm (ECDSA) is the arithmetic of blockchains, and asymmetric key cryptography is the means by which data transactions are encrypted by a sender and decrypted by a receiver using the paired public/private key method.
Over the past 30 years, ECC has become a key part of many current cryptosystems, cryptographic schemes and algorithms, e.g., Elliptic curve Diffie-Hellman (ECDH), Elliptic curve Integrated Encryption Scheme (ECIES), Elliptic curve Digital Signature Algorithm (ECDSA), Edwards-curve Digital Signature Algorithm (EdDSA), Elliptic curve Menezes-Qu-Vanstone (ECMQV), and Elliptic curve Qu-Vanstone (ECQV).
The elliptic curve digital signature algorithm (ECDSA) is used to prevent man-in-the-middle attacks [10] and to achieve mutual authentication between the tag and the reader.
