title = "Information-set decoding for linear codes over Fq",
abstract = "The best known non-structural attacks against code-based cryptosystems are based on information-set decoding. Stern's algorithm and its improvements are well optimized and the complexity is reasonably well understood. However, these algorithms only handle codes over F_2. This paper presents a generalization of Stern's information-set-decoding algorithm for decoding linear codes over arbitrary finite fields F_q and analyzes the complexity. This result makes it possible to compute the security of recently proposed code-based systems over non-binary fields. As an illustration, ranges of parameters for generalized McEliece cryptosystems using classical Goppa codes over F_31 are suggested for which the new information-set-decoding algorithm needs 2^128 bit operations.",
