Asymptotically, this error correcting capability meets the famous Gilbert—Varshamov bound. Retrieved from ” https: This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.

Binary Goppa codes have interesting properties suitable for cryptography in McEliece-like cryptosystems codex similar setups. We now know all we need to define the Goppa code:. Please help improve it or discuss these issues on the talk page. Please help gopoa clarify the article. We usually denote a Goppa code by C DG. Note that in binary case, locating the errors is sufficient to correct them, as there’s only one other value possible.

In mathematics and computer sciencethe binary Goppa code is an error-correcting code that belongs to the class of general Goppa codes originally described by Valerii Denisovich Goppabut the binary structure gives it several mathematical advantages over non-binary variants, codrs providing a better fit for common usage in computers and telecommunication.

This page was last edited on 14 Novemberat The following shows how the parameters of the code relate to classical parameters of linear systems of divisors D on C cf.

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.
