Verification of Operating Systems for Internet of Things in Smart Cities From the Assembly Perspective Using Isabelle/HOL

Formal verification can mathematically prove whether a software satisfies the requirements described in its design. In traditional software development, even if the software systems, especially the operating system for Internet of Things in smart cities, passes the verification test, it is difficult to explain its correctness. The implementation of formal verification after the design and development process proves that the software system meets the expected requirements. This will become a trend for future software development. In this paper, we model the system state of the X86 architecture on the assembly layer, and use a micro operating system prototype for Internet of Things in smart cities as an example to explain the proposed method that can verify operating systems for Internet of Things in smart cities on the assembly layer. The verification result shows that this method is feasible.
