The invention provides a PUF (Physical Unclonable Function)-based lightweight unmanned aerial vehicle identity authentication method, which is mainly used for low-power-consumption secure communication between resource-constrained devices, and is particularly suitable for communication between unmanned aerial vehicles and a local server and between unmanned aerial vehicles. According to the method, an efficient and safe identity authentication mechanism is provided by creatively combining PUF generation equipment uniqueness information, public key encryption (ECC), hash calculation and memory integrity verification. By introducing a random number and a timestamp mechanism, a replay attack is prevented, and an independent and safe session key is generated through negotiation. According to the scheme, a dynamic key updating mechanism is further introduced, updating of a PUF key is completed under the guidance of a server, the dynamism and safety of the authentication process are effectively enhanced, potential threats such as man-in-the-middle attack, replay attack and forgery attack are prevented, and the method can achieve rapid and safe identity authentication on an unmanned aerial vehicle platform with limited resources and limited computing power, and is high in practicability. And the reliability and the safety of identity authentication of the equipment are greatly improved.
本发明提供了一种基于PUF的轻量级无人机身份认证方法,主要用于资源受限设备之间的低功耗安全通信,尤其适用于无人机与本地服务器、无人机与无人机间的通信。该方法创新性地结合PUF生成设备唯一性信息、公钥加密(ECC)、哈希计算和内存完整性校验,提供高效且安全的身份认证机制。通过引入随机数和时间戳机制,防止重放攻击,并协商生成独立且安全的会话密钥。方案还引入了动态密钥更新机制,由服务器主导完成PUF密钥的更新,有效增强了认证过程的动态性和安全性,防止中间人攻击、重放攻击和伪造攻击等潜在威胁,该方法能够在资源受限、计算能力有限的无人机平台上实现快速、安全的身份认证,极大提高了设备身份认证的可靠性和安全性。
