Abstract

本申请实施例提供了一种根密钥保护方法和***，使能在基于安全两方计算中，容错3个以上节点中的任意两个节点发生故障，并且在2个节点参与计算的基础上，只增加一个节点就能容错任意一个节点发生故障，该方法在冗余节点上部署多份密钥材料，提高了根密钥保护方法的可靠性，并且保证了同一节点上的密钥材料无法恢复出根密钥，保证了安全性。该根密钥保护方法通过使用二进制标签对参与安全两方计算的节点进行分类，使能将参与安全两方计算的节点在协商密钥的过程中分为主节点和辅节点，其中主节点负责所有节点的密钥的生成，辅节点负责生成自身所需密钥，并且使得任意两个节点的密钥材料中的相同列的密钥材料的异或结果相同，即根密钥相同。
