Cryptohack elliptic curves

WebGenerally elliptic curves are defined over a field with a prime p, or F p, but in this case we working with the ring Z n. The rest of the question is a typical ECDLP (Elliptic Curve Discrete Log Problem) problem, where we're given a generator point G on the curve and the point s ∗ G, where s is our flag and the value we need to solve for. WebDescription Galois Counter Mode (GCM) is the most widely used block cipher mode in TLS today. It's an "authenticated encryption with associated data" cipher mode ( AEAD ), yet not resistant to misuse. See here for a great resource on the inner workings of GCM, as well as this attack. Help
