Side-Channel Attack against CRYSTALS-Kyber

Side-Channel
Attack
against
CRYSTALS-Kyber

CRYSTALS-Kyber
is
one
of
the
public-key
algorithms
currently

recommended
by
NIST
as
part
of
its
post-quantum
cryptography

standardization
process.

Researchers
have

just
published
a
side-channel
attack—using
power
consumption—against
an
implementation
of
the
algorithm
that
was
supposed
to
be
resistant
against
that
sort
of
attack.

The
algorithm
is
not
“broken”
or
“cracked”—despite

headlines
to
the
contrary—this
is
just
a
side-channel
attack.
What
makes
this
work
really
interesting
is
that
the
researchers
used
a
machine-learning
model
to
train
the
system
to
exploit
the
side
channel.
