Establishing trust between two devices

A device comprising:

• a processing system comprising:
• one or more processors;
• and
• memory coupled to the one or more processors, the processing system configured to:
• receive a certificate from a trusted entity device, the trusted entity device maintaining a list of devices that are trusted within a domain, and the list of devices including the device;
• and
• establish, based at least in part on the certificate, a connection with another device via a media access control (MAC) address.

A device comprising:

• a processing system comprising:
• one or more processors;
• and
• memory coupled to the one or more processors, the processing system configured to:
• issue a hash function and a hash seed to a first device, the hash seed and the hash function usable to generate a hash chain that includes multiple versions;
• receive, from a second device, a request to connect to the first device;
• determine a current version of the multiple versions of the hash chain that is being used by the first device to determine a media access control (MAC) address;
• and
• send, to the second device, the hash function, the hash seed and the current version thereby enabling the second device to determine the MAC address and connect to the first device via the MAC address.
