Evolution of trust systems from PCs to mobile devices: Building secured and trusted ecosystems

A trust ecosystem for mobile devices based on trusted computing principles is presented. The trust ecosystem model from the latest PC platform provides a reference for the evolution of a trust model for the diverse mobile device market. By balancing the trusted computing burden between the mobile device and network and separating service delivery/access control decisions and error reporting from remediation, the processing in the network is hugely simplified, and efficiency in the use of network resources is increased. Additionally, certification and accreditation of the mobile devices trust security capabilities provides a white box view into a mobile devices security architecture and a means to gain a high level of trust assurance in the mobile device.
