Subspace coding is a solution to the error-control problem in noncoherent networks using Random Linear Network Coding (RLNC) as a transmission mechanism. In this paper, we propose a secure error-correction scheme based on a codeword selection method called the Subspace Coding Strategy (SCS) along with a permutation step, as a possible solution for secure transmission of data encoded using subspace codes. Our scheme also makes use of the correction capability of the used code to induce correctable random errors to further mislead the wiretapper. Numerical results and comparative analysis with other schemes from the literature are presented as a verification of the impact of the proposed scheme on transmission security.

子空间编码是使用随机线性网络编码 (RLNC) 作为传输机制的非相干网络中的错误控制问题的解决方案。在本文中，我们提出了一种基于称为子空间编码策略 (SCS) 的码字选择方法以及置换步骤的安全纠错方案，作为安全传输使用子空间代码编码的数据的可能解决方案。我们的方案还利用所用代码的纠正能力来引入可纠正的随机错误，以进一步误导窃听者。数值结果和与文献中其他方案的比较分析被提出来验证所提出的方案对传输安全的影响。
