Abstract

Techniques are disclosed relating to securely authenticating communicating devices. In various embodiments, a computing device receives, via a network connection with a network, a first certificate for a first public key pair of the computing device. The computing device provides the first certificate to an offline accessory device and receives a second certificate for a second public key pair maintained by the offline accessory device. The computing device performs a verification of the second certificate and, responsive to the verification being successful, interacts with the offline accessory device. In some embodiments, prior to providing the first certificate, the computing device determines an ordering in which the first and second certificates are to be exchanged by the first computing device and the offline accessory device, and the first certificate is provided to the offline accessory device in accordance with the determined ordering.

Dependent claims

A non-transitory computer readable medium having program instructions stored therein that are executable by an offline accessory device to cause the offline accessory device to perform operations comprising:

detecting a first computing device via a network interface;
in response to the detecting, determining to delay providing a second certificate of the offline accessory device until after a first certificate of the first computing device has been received and verified;
receiving the first certificate from the first computing device, wherein the first certificate is for a first public key pair of the first computing device;
performing a verification of the first certificate;
responsive to the verification of the first certificate:
providing the second certificate stored by the offline accessory device to the first computing device, wherein the second certificate is for a second public key pair for the offline accessory device;
and
enabling interaction with the first computing device.
