Abstract
Techniques for secure pairing for devices with Near Field Communications (NFC) tags equipped with authentication are provided. In one aspect a device with a passive near field communication tag including a private key for authentication is provided. The device may send a challenge request to a host device including an active NFC tag via a wireless communication protocol. The challenge request may be combined with a shared secret value known to the device and the host device to create a challenge request seed. The challenge request seed may be combined with the private key to compute a verified challenge request response. A challenge request response may be received from the host device via the wireless communication protocol. The challenge request response and verified challenge request response may be compared to authenticate the host device to the device.
