The invention provides a smart contract-driven unmanned aerial vehicle operation data sharing method and a related device, and relates to the field of unmanned aerial vehicles. The unmanned aerial vehicle converts the identity information of each subscription user of the unmanned aerial vehicle into an anonymous identifier of each subscription user, and generates a broadcast header including the anonymous identifier of each subscription user; selecting a key generation element from the large prime order integer group, and generating a symmetric key of the shared data according to the key generation element and a preset bilinear mapping value; converting the shared data into an encrypted ciphertext through the symmetric key, and generating signature information of the encrypted ciphertext and the broadcast header; and packaging the signature information, the encrypted ciphertext and the broadcast header into a broadcast ciphertext, and broadcasting the broadcast ciphertext to terminal equipment of each subscription user. Therefore, the unmanned aerial vehicle supports dynamic subscription, and the identity information of the subscription user is hidden through the one-way anonymous key protocol. In addition, a lightweight responsibility-asking mechanism is realized through a responsibility-asking smart contract and a short signature deployed on a private chain.

    本申请提供一种智能合约驱动的无人机运行数据共享方法及相关装置,涉及无人机领域。无人机分别将无人机的每个订阅用户的身份信息转换为每个订阅用户的匿名标识,并生成包括每个订阅用户的匿名标识的广播头;从大素数阶整数群中选取密钥生成元素,并根据密钥生成元素以及预设的双线性映射值,生成共享数据的对称密钥;通过对称密钥将共享数据转换为加密密文,并生成加密密文与广播头的签名信息;将签名信息、加密密文与广播头封装为广播密文,并广播给每个订阅用户的终端设备。如此,使得无人机支持动态订阅,并通过单向匿名密钥协议隐藏了订阅用户的身份信息。此外,还通过部署在私链上的问责智能合约和短签名实现了轻量级的问责机制。
