Simple explanation for Elliptic Curve Cryptographic

The key generation in the ECC cryptography is as simple as securely generating a random integer in certain range, so it is extremely fast. Any number within the range is valid ECC private key. The public keys in the ECC are EC points - pairs of integer coordinates {x, y}, laying on the curve. Due to their special properties, EC points can be compressed to just one coordinate + 1 bit (odd or.

Key and signature-size comparison to DSA. As with elliptic-curve cryptography in general, the bit size of the public key believed to be needed for ECDSA is about twice the size of the security level, in bits.
