Binary Goppa code
Because of the high error correction capacity compared to code rate and form of parity-check matrix which is usually hardly distinguishable from a random binary matrix of full rankthe binary Goppa codes are used in several post-quantum cryptosystemsnotably McEliece cryptosystem and Niederreiter cryptosystem.
