This standard defines a technique for generating and validating digital signatures. It is also the elliptic curve analog of the Digital Signature Algorithm (DSA) (ANSI X9.30 Part 1) Elliptic cure systems are public-key (asymmetric) cryptographic algorithms that are typically used to create digital signatures (in conjunction with a hash algorithm), and to establish secret keys securely for use in symmetric-key cryptosystems.
