Groups and Finite Fields – Crypto Theoretical Minimum

Download pdf here: Groups and Finite Fields 1. Introduction Group, field and elliptic curve theories make a regular appearance in the study of crypto-assets including but not limited to cryptocurrencies. For example, the security strength of a number of crypto-specific primitives relies on the math of elliptic curve groups over finite fields. These groups constitute a …

LSAG Signature Scheme

Download pdf here: LSAG Signature Scheme 1. Introduction For a given ring size , Cryptonote’s original scheme (as introduced in part 5), generates signatures of the form consisting of arguments. It turns out that a more efficient scheme initially introduce in [3] and later adapted by Adam Back in [1] can achieve the same security properties …
