AI Technical Summary
[0003]现有运维认证机制多以账号权限、通信通道加密或静态令牌为核心,难以对设备实时运行状态、当前运维指令语义、设备硬件唯一性以及业务场景上下文进行联合校验,无法充分适应多源异构设备协同管理下的安全需求
[0018] This invention integrates device operating status snapshots, maintenance operation instructions, and the concealed features of the device's factory serial number to construct a payload authentication polynomial on a Galois domain with large prime numbers. This allows maintenance instructions to participate in token generation in the form of polynomial payload features, preventing the instruction content from appearing directly in plaintext. Simultaneously, it combines state digests, authentication anchors, random numbers, formal derivatives, and multi-round hash cyclic shifts to generate token signatures, increasing the difficulty of unauthorized parsing, tampering, forgery, and replaying of tokens. The target security device completes instruction authentication and parsing through candidate finite field verification, polynomial evaluation, state digest reconstruction, signature comparison, authentication anchor verification, and token replay verification, thereby improving the authenticity, integrity, non-impersonation capability, and execution reliability of remote maintenance instructions.
