A fully featured EMV Level 2 Kernel for Embedded Systems
EMV.LIB - Chip and PIN / EMV Level 2 for the Embedded Environment Developing EMV
Level 2 Kernel technology for embedded systems, or those based around a
non-Windows operating system, presents its own unique set of challenges,
particularly as many of the terminals that require the addition of EMV Level 2
functionality were not designed with CPU intensive encryption and hashing in
mind.
The EMV specifications offer some flexibility in how these challenges are met by
enabling certain terminal types to avoid the use of the more processor intensive
elements, such as the RSA encryption used in Data Authentication. However it
does not solve the problem of how to add the remaining functionality.
CreditCall’s solution to this problem was to develop an EMV Level 2 Kernel in
strict ANSI C with all of the hardware and operating system specific
functionality abstracted away from the core functions of the Kernel through the
use of the EMV.LIB Hardware Abstraction Layer (HAL).
This architecture and the use of ANSI C means that EMV.LIB can be ported to
virtually any environment for which there is a suitable C compiler. This
approach has enabled this version of the CreditCall EMV Kernel to become the
critical component in many Chip and PIN solutions and is now the most widely
certified EMV Level 2 Kernel available today.
To date EMV.LIB has been compiled on everything from a Zilog Z180 right the
way through to more recent microprocessors such as the ARM 7 and 9 series.
The Hardware Abstraction Layer is empty function, each function deals with an
element of EMV that cannot be addressed in a manner that is platform
independent. Once these functions have been populated, the Kernel can be
compiled for the target platform. The resulting Object code can then be linked
with the payment application to create a fully functional EMV Level 2 compliant
solution.
Key highlights of EMV.LIB
- Very small memory footprint, stack and resource utilisation.
- Compile in or out blocks of EMV functionality to suit your target
platform and EMV ICS.
- Specific optimisations for smaller 8 and 16 bit CPUs.
- Hardware Abstraction Layer (HAL) enables easy integration into
target platform.
- Endian indifferent.
- Caters for older compiler quirks such as short variable and
function names.
