Methodologies for Designing Power-Aware Smart Card Systems

pdf-format:


Abstract

Smart cards are some of the smallest
computing platforms in use today. They have
limited resources, but a huge number of
functional requirements. The requirement for
multi-application cards increases the demand
for high performance and security even more,
whereas the limits given by size and energy
consumption remain constant.

We describe new
methodologies for designing and implementing
entire systems with regard to power awareness
and required performance. To make use of this
power-saving potential, also the higher layers
of the system - the operating system layer and
the application domain layer - are required to
be designed together with the rest of the
system.

HW/SW co-design methodologies enable the gain of
system-level optimization. The first part presents the
abstraction of smart cards to optimize system architecture
and memory system. Both functional and transactional-level
models are presented and discussed. The proposed design
flow and preliminary results of the evaluation are depicted.

Another central part of this methodology is a cycle-accurate instruction-set
simulator for secure software development.
The underlaying energy model is designed
to decouple instruction and data dependent energy dissipation,
which leads to an independent characterization process and allows
stepwise model refinement to increase estimation accuracy. The
model has been evaluated for a high-performance smart card CPU and
an use-case for secure software is given.
