论文摘要
我们考虑了基于模块的密钥封装机制（KEM），在8维晶格$ e_8 $上进行对帐，该质量是快速CVP算法。我们的方案生成256位密钥，每个维度需要3或4位对帐。我们表明，它可以在模量Q方面均优于Kyber，并具有可比的误差概率。我们证明我们的协议是IND-CPA安全的，并将Kyber的安全水平提高了7.3％。
We consider a key encapsulation mechanism (KEM) based on Module-LWE where reconciliation is performed on the 8-dimensional lattice $E_8$, which admits a fast CVP algorithm. Our scheme generates 256 bits of key and requires 3 or 4 bits of reconciliation per dimension. We show that it can outperform Kyber in terms of the modulus q with comparable error probability. We prove that our protocol is IND-CPA secure and improves the security level of Kyber by 7.3%.
