Goppa code

The following shows goppx the parameters of the code relate to classical parameters of linear systems of divisors D on C cf. In non-binary cases a separate error correction polynomial has to be computed as well. Such codes were introduced by Valerii Denisovich Goppa.

They should not be confused with Binary Goppa codes that are used, for instance, in the McEliece cryptosystem.

In particular cases, they can have interesting extremal properties. Retrieved from ” https: 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 ogppa Goppa codes are used in several post-quantum cryptosystemsnotably McEliece cryptosystem and Niederreiter cryptosystem.

Riemann—Roch theorem for more. Note that in binary case, locating the errors is sufficient to correct them, as there’s only one other value possible. Retrieved from ” https: The notation l D means the dimension of L D.

In mathematics gopppa 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, also providing a better fit for common usage in computers and telecommunication.
