广义秩权与汉明权的相似性及其在网络编码中的应用

On the similarities between generalized rank and Hamming weights and their applications to network coding

Umberto Martínez-Peñas

摘要:

秩权重和广义秩权重已经被证明可以表征线性网络编码中的错误和擦除校正以及信息泄漏,就像汉明权重和广义汉明权重描述经典错误和擦除校正以及II型窃听信道和基于代码的秘密共享中的信息泄漏一样。虽然这两种情况之间的许多相似之处已经在文献中建立和证明,但Hamming情况下的许多其他已知结果,例如保权映射的边界或特征,尚未转化为秩情况,或者在某些情况下已经在开发不同的机器后得到证明。本文的目的是进一步将权重和广义权重联系起来,表明这两种情况下的结果和证明通常基本相同,并看到这些相似性在网络编码中的意义。秩情况下的一些新结果在汉明情况下也有新的后果。

英文摘要:

Rank weights and generalized rank weights have been proven to characterize error and erasure correction, and information leakage in linear network coding, in the same way as Hamming weights and generalized Hamming weights describe classical error and erasure correction, and information leakage in wire-tap channels of type II and code-based secret sharing. Although many similarities between both cases have been established and proven in the literature, many other known results in the Hamming case, such as bounds or characterizations of weight-preserving maps, have not been translated to the rank case yet, or in some cases have been proven after developing a different machinery. The aim of this paper is to further relate both weights and generalized weights, show that the results and proofs in both cases are usually essentially the same, and see the significance of these similarities in network coding. Some of the new results in the rank case also have new consequences in the Hamming case.
