NTAG 413 DNA 带来了AES密码认证，彻底改变了NTAG的产品组合，只需感应标签就可以自动安全地连接到网络服务，而无需在移动NFC设备上安装专用应用程序。

NTAG 413 DNA revolutionizes NTAG product portfolio by bringing AES cryptographicauthentication and allows to automatically and securely connect to a web service by just tapping the tag without the need of a dedicated app installed on the mobile NFC device.

除NXP原创签名和三道双向认证之外，它还引入了一种新的安全特性，称为“安全唯一的NFC消息(SUN)”，它在每次读取时自动生成tap-unique标签认证数据，从而根据预定义的标准为每个用户提供专用的唯一通信。不需要任何应用程序(在NFC设备中)来生成这种tap-唯一数据，该数据由芯片UID、tap计数器和包含的数据所导出的CMACed信息组成。支持NFC的设备可以自动连接到基于网络的服务，并且基于包含在网址中的信息，设备可以检查标签的真实性并验证信息的有效性。NTAG 413为个性化这一独特数据集的结构提供了灵活性。

Besides the NXP originality signature and a 3-pass mutual authentication, it introduces a novel security feature called “Secure Unique NFC Message (SUN)”, which automatically generates tap-unique tag authentication data upon each read-out what enables dedicated unique communication to each user based on predefined criteria. No app(in NFC device) is required to generate this tap-unique data consisting of CMACed information derived from the chip UID, a tap counter and contained data. An NFC enabled device can automatically connect to a web based service and based on the information contained in URL, the device can check the tags authenticity and verify the information validity. NTAG 413 DNA offers flexibility to individualize the structure of this unique data set.

NTAG 413 DNA是完全符合NFC Forum标签的4类兼容IC，并且也符合ISO/IEC14443-4，ISO/IEC 7816-4文件结构和APDU格式。由于NTAG 413 DNA标签IC具有高输入电容(70pF)，因此该产品尤为适用于要求具有小尺寸的应用，而不会降低性能。小型NFC标签可更轻松地嵌入产品标签或电子设备等目标中。

NTAG 413 DNA is certified as NFC Forum Type 4 Tag and is also compliant to ISO/IEC14443-4 , ISO/IEC 7816-4  file structure and APDUs format. Thanks to the high input capacitance (70pF), NTAG 413 DNA tag IC isparticularly tailored for applications requiring small footprints, without compromise on performance. Small NFC tags can be more easily embedded into e.g. product labels orelectronic devices.
