Query: Formal verification of a software countermeasure against instruction
  skip attacks   Fault attacks against embedded circuits enabled to define many new attack
paths against secure circuits. Every attack path relies on a specific fault
model which defines the type of faults that the attacker can perform. On
embedded processors, a fault model consisting in an assembly instruction skip
can be very useful for an attacker and has been obtained by using several fault
injection means. To avoid this threat, some countermeasure schemes which rely
on temporal redundancy have been proposed. Nevertheless, double fault injection
in a long enough time interval is practical and can bypass those countermeasure
schemes. Some fine-grained countermeasure schemes have also been proposed for
specific instructions. However, to the best of our knowledge, no approach that
enables to secure a generic assembly program in order to make it fault-tolerant
to instruction skip attacks has been formally proven yet. In this paper, we
provide a fault-tolerant replacement sequence for almost all the instructions
of the Thumb-2 instruction set and provide a formal verification for this fault
tolerance. This simple transformation enables to add a reasonably good security
level to an embedded program and makes practical fault injection attacks much
harder to achieve.
