APPENDIX C: TDES Key Installation
TDES Master Key Installation
Triple - Data Encryption Standard or TDES was designed as a way to strengthen the
security of the master key by upgrading from a 16 bit key to a 32 bit key. In addition to
the required software changes to support the TDES, the specification calls for a pin-pad
to encrypt any data sent between the keypad and the CPU. In this new configuration the
master keys are stored securely within the pin-pad, rather than the mainboard as done
previously.
