Machine-to-machine (M2M) communication is viewed as one of the next frontiers in wireless communications. M2M communication applications and scenarios are growing and lead the way to new business cases. Because of the nature of M2M scenarios, involving unguarded, distributed devices, new security threats emerge. The use case scenarios for M2M communication also address the new requirement on flexibility, because of deployment scenarios of the M2ME in the field. We believe that these new requirements require a paradigm shift. One important pillar of such a shift will be a new, more balanced mix of device-centric trust and traditional enforcement of security properties.
