For example, deterministic nonces were proposed in 1997, are integrated into modern signature mechanisms such as EdDSA, and would have prevented the 2010 Sony PlayStation ECDSA security disaster. However, this security issue does not interact with curve choices, so it is outside the scope of SafeCurves.
ECDSA. The Elliptic Curve Digital Signature Algorithm (ECDSA) was introduced as the preferred algorithm for authentication in OpenSSH 5.7. Some vendors also disable the required implementations due to potential patent issues. There are two sorts of concerns with it:
The Elliptic-Curve Digital Signature Algorithm (ECDSA) is a Digital Signature Scheme based on ECC. ECDSA was first proposed in 1992 by Scott Vanstone in response of NIST (Nation Institute of Standards and Technology) request for public comments on their proposal for Digital Signature Schemes.
Nov 23, 2015 · Any simple implementation will seem to work but leak secrets through side channels. Disabling them doesn't seem to cause a problem; clients either have Curve25519 too, or they have good enough DH support. And ECDSA (or regular DSA for that matter) is just not a good algorithm, no matter what curve you use.

The Elliptic Curve Digital Signature Algorithm (ECDSA) is the elliptic curve analogue of the Digital Signature Algorithm (DSA). It was accepted in 1999 as an ANSI standard, and was accepted in 2000 as IEEE and NIST standards. It was also accepted in 1998 as an ISO standard, and is under consideration for inclusion in some other ISO standards.The ECDSA signature method is the elliptic curve equivalent of the DSA method and is used extensively with Bitcoin methods. With this, we create a private key (priv) and then generate a public key ...

An optimal ECDSA implementation will use public key-based security 3 and a certificate infrastructure along with a digital signature for authentication. In this scenario, the programmable logic controller (PLC) first verifies the certificate of the sensor card to ensure that it is a legitimate member of that particular ecosystem.
A DSA or ECDSA private key is an integer 'x' taken modulo q. The relevant standards prescribe that x shall not be 0; hence, x is an integer in the range [1, q-1]. A DSA or ECDSA public key is computed from the private key x, and the key parameters: For DSA, the public key is the integer: y = g^x mod p
