5G-ENSURE - D2.2 Trust model (draft) [PDF]

, 2016
Trust is a response to risk. A decision to trust someone (or something) is a decision to accept the risk that they will not perform as expected. To manage risk in a socio-technical system such as a mobile network we need to understand what trust ...
