你好：
我司已经签署保密协议，但是不知道如何使用natg424 uid与公钥，Read_Sig获取的56字节签名在嵌入式硬件平台实现ECDSA验证。文档上an11350没有详细步骤实现ECDSA verification(secp224r1),能否告诉我申请哪些资料来实现，谢谢。
你好@qinzhi
希望你一切都好。
非常抱歉，用作 NTAG 签名验证参考，引用的应用笔记 (AN11350) 适用于其他具有 32 字节签名和不同曲线的 NTAG 产品。
NTAG 424 DNA 和 NTAG 424 DNA TagTamper 特性和提示第 7.2 节描述了非对称签名验证的可用程序。但是，由于 ECDSA 验证程序是在卡片之外进行的，因此没有关于 ECDSA 验证的具体信息。
对于给您带来的不便，我再次深表歉意。
问候，
爱德华多。
