一种数字车钥匙密钥分布式安全管理方法

本发明公开了一种数字车钥匙密钥分布式安全管理方法。本发明中，通过固定置换矩阵的随机排列特性，让步态特征向量的比特映射关系完全无规律可循，结合SM4对称加密算法生成的第一动态验证因子，非授权用户即使获取步态特征数据，也无法通过逆向推导还原验证因子；同时GNSS与IMU融合定位采用的加权卡尔曼滤波算法，通过信噪比动态调整观测数据权重，确保在复杂场景下仍能输出高精度的三维位置坐标，让第三动态验证因子与实时物理位置深度绑定。两者联动构建的分布式密钥分片体系，将完整根密钥拆分为三个独立分片分别存储于车载安全芯片、移动设备与云端服务器，杜绝了单点密钥泄露导致的系统安全风险，从而提高了整体方法的安全可靠性。
