Methods, systems, and computer-readable storage media for a trust management system (TMS) in connected devices including a service provider device and a service consumer device, actions including receiving, by the TMS, side information associated with the service provider device, the side information including profile data and context data, processing, by the TMS, the side information using a computer-executable stereotype model to determine a prior trust value, determining, by the TMS, a trust value using a computer-executable experiential trust model, and at least partially based on the prior trust value, and selectively conducting a transaction between the service consumer device, and the service provider device based on the trust value.
