In the Omni 7xxx platform, the IPP7 was implemented in hardware. In the M
x
800
series of terminals, the IPP chip is emulated in software. The application interface
is similar to the one in the Vx family of terminals.
Applications access the IPP through a virtual communication port.
The M
x
800 series terminal IPP emulation contains most IPP7/IPP8 features,
including 3DES master/session, multiple DUKPT, and MAC processing. It does
not support the Spain, Interac, or Secure Messaging modes.
For information on the supported IPP packets, refer to Appendix A.
All IPP functions are defined in the header file svcsec.h. Applications must link
with the libvfisec.so library by using -lvfisec.
