Blockchain Technology, Lecture 5: Elliptic Curve Cryptography
In this Lecture 5, the mathematical principle of elliptic curve cryptography (ECC) is explained for blockchains. Specifically, the historical development of cryptography from scytale cipher to Enigma machine and to public-key cryptography, symmetric and asymmetric cryptography, Arthur Scherbius, codebook, Alan Turing, decoding, modular arithmetic, group, finite field, Galois, Abel, elliptic curve arithmetic, public key generation, compressed and uncompressed public keys, bitcoin address generation, digital signature, ECDSA, transaction script code, authorized certificate, credit cards, magnetic stripe cards, smart IC cards, contact and noncontact IC cards, transit cards, and USIM chips are explained.
