 Using the function `ownerEngagement`, the asset sends the hash of $K_A$, and if it is the same as the data in `hashK_OA`, then the state of the token changes to `engagedWithOwner` and the event `OwnerEngaged` are sent. Once the asset receives the event, it changes its operation mode to `engagedWithOwner`. This process is shown in `Figure 4`. From this moment, the asset can be managed by the owner and they can communicate in a secure way using the shared key.
