McEliece Cryptosystem - Attacks - Information Set Decoding
... be the most effective attacks against the McEliece and Niederreiter cryptosystems ... a practical attack on the original McEliece cryptosystem, based on finding low-weight code words using an algorithm published by Jacques Stern in 1989 ... Using the parameters originally suggested by McEliece, the attack could be carried out in 260.55 bit operations ...

Niederreiter Cryptosystem
... the Niederreiter cryptosystem is a variation of the McEliece Cryptosystem developed in 1986 by Harald Niederreiter ... Niederreiter is equivalent to McEliece from a security point of view ... Niederreiter is about ten times faster than the encryption of McEliece ...
