关于高斯窃听编码中格的吻数的一点注记

A short note on the kissing number of the lattice in Gaussian wiretap coding

Anne-Maria Ernvall-Hytönen

摘要:

证明了在$n=24m+8k$维偶幺模格上,若最短向量长度为$\geq 2m$,则随着长度为$2m$的向量数的减少,保密增益增加.我们也将在一般的幺模格上证明一个类似的结果。此外,假设Belfiore和Solé的猜想,我们将计算随着向量数量的变化,保密增益的逆之间的差异。最后,我们将通过一个例子证明,存在两个相同维数的格,它们具有相同的最短向量长度和相同的接吻数,但具有不同的保密增益。

英文摘要:

We show that on an $n=24m+8k$-dimensional even unimodular lattice, if the shortest vector length is $\geq 2m$, then as the number of vectors of length $2m$ decreases, the secrecy gain increases. We will also prove a similar result on general unimodular lattices. Furthermore, assuming the conjecture by Belfiore and Solé, we will calculate the difference between inverses of secrecy gains as the number of vectors varies. Finally, we will show by an example that there exist two lattices in the same dimension with the same shortest vector length and the same kissing number, but different secrecy gains.
