Ambient Intelligence
Integration leads a high degree of complexity
Ensuring correctness is essential
We proposed a design time Formal Verification methodology

Against every posted request the specific TS must receive an acknowledgment
TS will be available at anytime
Interruption from any TS cannot break/change the execution of the current task
Direct Access to the Bank is not possible

Property 1: Against every posted request the specific TS must receive an acknowledgment
◦ AG [openRequest(T1)] AF {tsDone(T1)} true
Property 2: TS will be available at anytime
◦ AG [openRequest(T1)] true
◦ AG [openRequest(T1)] A [true {~ openRequest(T1) } U {tsDone(T1)} true]
12
Property 3: Interruption from any TS cannot break/change the execution of the current task
◦ AG [openRequest(T1)] AF [openRequest(T2)] A[true {~ daDoorOpen (DAExt) } U {tsDone(T1)} true]
◦ AG [openRequest(T1)] AF [openRequest(T3)] A[true {~ daDoorOpen (DAInner) } U {tsDone(T1)} true]
◦ AG [openRequest(T1)] AF [openRequest(T4)] A[true {~ daDoorOpen (DAInner) } U {tsDone(T1)} true]
13
Property 4: Direct Access to the Bank is not possible
◦ AG [daDoorOpen(DAExt)] A[true {~ daDoorOpen (DAInner)} U {extDoorClosed()} ]
◦ AG [daDoorOpen(DAInner)] A[true {~ daDoorOpen (DAExt)} U {innerDoorClosed()} ]

Verification => requirements satisfaction,safety, security
The presented methodology ensures◦ the correct behavior of these IDEs
with the use of Formal Model Checking technique.
