Abstract
本发明公开了一种基于量子密钥分发的硬件隔离认证装置，并公开了对应的交互方法。该装置在CPU前端部署FPGA硬件认证层，构筑不可绕过的安全屏障，彻底杜绝恶意数据包直接攻击CPU的风险。利用量子密钥的不可复制性和动态更新特性，结合硬件级认证机制，从根本上解决了传统五元组过滤策略易被伪造攻击穿透的安全缺陷。为设备内部及设备间通信提供基于硬件的强身份认证和端到端加密，确保数据传输的机密性与完整性。FPGA硬件并行处理安全算法，将CPU从繁重的加密运算中完全解放，实现安全处理的“零开销”，同时保障通信高效性。采用量子密钥分发提供信息理论安全的基础密钥，从根本上解决了传统软件加密方案中静态密钥或动态密钥可能被窃取的安全隐患。
