Is there any point in trying to figure out "can you trust"? To me that seems like some kind of code

In doing some digging (and I may be totally off) TRUST stands for Transparent Reconfiguration Ubiquitous Terminal.

In doing some more digging I came across this:

To date, research into reconfigurable mobile communications has predominantly focussed on the software radio concept, and specifically on the hardware technologies required to move physical layer processing into a programmable environment. Although an interesting and necessary challenge, this only represents a fraction of the overall support and technology required to realise the potential of the concept. Other necessary developments include network/terminal cooperation for seamless inter-standard handoff, QoS management, a secure software download mechanism, terminal software architecture supporting reconfiguration, configuration management, capability negotiation. Summarising results from early IST-TRUST (Transparently Reconfigurable Ubiquitous terminal) project deliverables, this paper describes the likely overall system environment, and the key technical challenges to be researched in TRUST for realising a reconfigurable terminal to meet the needs of users within that environment

Not sure if this means anything. But thought I'd share
