Learning crypto: The Elliptic Curve Digital Signature Algorithm

cryptog-a

  In today’s installment, we’ll be studying the elliptic curve digital signature algorithm (ECDSA) used by bitcoin.  It is the method that cryptocurrency uses to mathematically prove that one has the right to spend coin. Hopefully, you took the opportunity to understand the Diffie-Hellman-Merkle secret key exchange, which I wrote about previously. As in the DHM algorithm, the elliptic curve algorithm utilizes asymmetric cryptography, ...
