The IEEE Computer Society &  Computational Intelligence Society (CS/CIS) Rochester Chapter has a speaker presentation at the Section’s joint chapters meeting (JCM) on April 9th, 2019. The technical sessions are free to attend.  Reservations are required to attend the dinner and keynote presentation with an associated cost.  Please find details and register for the JCM at:  https://meetings.vtools.ieee.org/m/190998

 


CS/CIS presentation:  Cache Side-Channel Attack and Defense on Mobile and IoT Devices

ABSTRACT:

It is found that existing and powerful cache side-channel attacks
on Intel architectures, including Prime+Probe, are ineffective on
mobile and Internet-of-things (IoT) devices powered by ARM architectures.
The trust in ARM’s hardware-isolated execution environments, namely
TrustZone, was also reinforced by these findings. However, those
discoveries do not rule out novel and more sophisticated cache
side-channel attacks that leverage overlooked hardware features.
In this talk, I will present a novel Prime+Count attack that can be
used to build reliable covert channels between the normal and secure
world of TrustZone, which breaks one of its fundamental security
guarantees.

On the other hand, protections that can defeat previous cache
side-channel attacks on Intel architectures are not necessarily
effective in mitigating novel cache attacks on ARM platforms. Such
solutions attempt to mitigate attacks by explicitly or implicitly
creating a private space, in which constant-time access to sensitive
data is assured. However, some of the attempts utilize hardware
features available only on certain Intel processors. In this talk,
I will also discuss a defense against cache side-channel attacks
that can protect against both dedicated cache (L1) and shared cache
(L2) attacks on mobile and IoT devices.
