Title:
On the Automatic Construction of Indistinguishable Operations

Authors: Manuel Barbosa, Dan Page

Abstract:

An increasingly important design constraint for software running on ubiquitous
computing devices is security, particularly against physical methods such as
side-channel attack. One well studied methodology for defending against such
attacks is the concept of indistinguishable functions which leak no
information about program control flow since all execution paths are
computationally identical. However, the constructing such functions by hand
is laborious and error prone as their complexity increases. We investigate
techniques for automating this process and find that effective solutions can
be constructed with only minor amounts of computational effort.
