Secure protocol for peer-to-peer network

A computing device comprising:

• a radio;
• at least one processor;
• and
• computer storage medium storing computer-executable components for execution on the at least on processor, the computer-executable components comprising:
• a peer-to-peer control component configured to operate the computing device as a group owner of a peer-to-peer group of multiple remote devices, and to control the peer-to-peer group in accordance with a peer-to-peer protocol;
• a key generator, the key generator configured to provide a master key to each of the multiple remote devices, wherein the master key for each of the multiple remote devices is different than the master key for every other remote device of the multiple remote devices;
• and
• an authentication component, the authentication component configured to:
• determine whether a remote device attempting to join the peer-to-peer group has a valid master key;
• and
• in response to a determination that the remote device attempting to join the peer-to-peer group has the valid master key, generate a transient key for the remote device based on the valid master key.

At least one computer readable storage medium comprising a memory, or a disk, that stores computer executable instructions that, when executed by a processor of a controller device, perform a method comprising:

• performing a key generation process with each of a plurality of remote devices, the key generation process comprising, for each remote device of the plurality of remote devices:
• providing a master key to that remote device;
• and
• storing the master key for that remote device in a key store;
• forming, as a controlling member, a peer-to-peer group of the controller device and at least a subset of the plurality of remote devices, the forming comprising, for each remote device in the subset:
• authenticating that remote device based on the master key stored in the key store for that remote device;
• and
• generating a transient key for that remote device based on the master key stored in the key store for that remote device;
• and
• exchanging data with the remote devices in the peer-to-peer group, the exchanging comprising, for one or more remote devices in the group:
• encrypting data to be sent to that remote device with the transient key generated for that remote device.
