There are two fundamentally different authentication schemes: symmetric systems, which rely on secret keys shared by host and authenticator, and asymmetric systems, such as the Elliptic Curve Digital ...

ANNAPOLIS, Md.--(BUSINESS WIRE)--The Accredited Standards Committee X9 Inc. (X9) today announced that it has published a new standard, X9.142, The Elliptic Curve Digital Signature Algorithm (ECDSA).

Digital signatures are used to verify that electronic messages and data have come from the proper sender and to irrevocably certify that data was not tampered with or changed during transition from ...

The elliptic curve discrete logarithm problem (ECDLP) lies at the heart of modern public-key cryptography. It concerns the challenge of determining an unknown scalar multiplier given two points on an ...
