Algebraic structure of the minimal support codewords set of some linear codes

چکیده
It has been widely known that complete decoding for binary linear codes can be regarded as an linear integer programming problem with binary arithmetic conditions. Conti and Traverso [8] have proposed an efficient algorithm which uses Gröbner bases to solve integer programming with ordinary integer arithmetic conditions. Ikegami and Kaji [11] extended the Conti-Traverso algorithm to solve integer programming with modulo arithmetic conditions. It is natural to consider for those problems the Graver basis associated to them which turns to be the minimal cycles of the matroid associated to the code, i.e. minimal support codewords in the binary case and its geometry. This provides us an universal test set for the programs considered.

Binary Cyclic Codes and Minimal Codewords
Cyclic codes form an important class of codes. They have very interesting algebraic structure. Furthermore, they are equivalent to many important codes, such as binary Hamming codes, Golay codes and BCH codes. Minimal codewords in linear codes are widely used in constructing decoding algorithms and studying linear secret sharing scheme. In this paper, we show that in the binary cyclic code all ...
متن کاملEfficient Computation of the Set of Codewords of Minimal Support
In order to obtain the set of codewords of minimal support of codes defined over Zq we must compute a Graver basis of the ideal associated to such codes, see [9]. The main aim of this article is to reduce the complexity of the previous algorithm taking advantage of the powerful decomposition theory for linear codes provided by the decomposition theory of representable matroids over finite field...
متن کاملMulti-receiver Authentication Scheme for Multiple Messages Based on Linear Codes
In this paper, we construct an authentication scheme for multi-receivers and multiple messages based on a linear code C. This construction can be regarded as a generalization of the authentication scheme given by Safavi-Naini and Wang [8]. Actually, we notice that the scheme of Safavi-Naini and Wang is constructed with Reed-Solomon codes. The generalization to linear codes has the similar advan...
متن کاملAn Authentication Scheme for Subspace Codes over Network Based on Linear Codes
Network coding provides the advantage of maximizing the usage of network resources, and has great application prospects in future network communications. However, the properties of network coding also make the pollution attack more serious. In this paper, we give an unconditional secure authentication scheme for network coding based on a linear code C. Safavi-Naini and Wang [1] gave an authenti...
متن کاملOn the weak order ideal associated to linear codes
In this work we study a weak order ideal associated with the coset leaders of a non-binary linear code. This set allows the incrementally computation of the coset leaders and the definitions of the set of leader codewords. This set of codewords has some nice properties related to the monotonicity of the weight compatible order on the generalized support of a vector in F q which allows to descri...
