1. A method of managing a first connected device comprising:

  • receiving, at a communications interface of a first connected device from a second connected device associated with a first entity, a request to update a security association record stored in a non-transitory computer readable storage medium included in the first connected device;

    determining, based on the security association record, that the first connected device is not associated with an entity;

    receiving, at the communications interface of the first connected device from the second connected device, a first group token associated with the first entity;

    updating, based on receiving the first group token associated with the first entity, the security association record to indicate that the first connected device is associated with the first entity;

    receiving a message from a third connected device, the message comprising a second group token;

    comparing the first group token and the second group token to determine that the first group token and the second group token are the same; and

    updating the security association record to indicate that the third connected device is associated with the first entity based on determining that the first group token and the second group token are the same, thereby establishing a trusted connection between the first connected device and the third connected device.
