Systems and methods may provide for determining a first key associated with a first group and determining a first resource exposure policy for the device with respect to the first group. Additionally, the first key may be used to send first operational and security context data to a first dynamic group verifier in accordance with the first resource exposure policy. In one example, a second key associated with a second group is determined, a second resource exposure policy is determined for the device with respect to the second group, a local context change is detected, and the second key is used to send, in response to the local context change, second operational data to a second dynamic group verifier in accordance with the second resource exposure policy.
