User Manual
1.8.2.3
Tamper evidence
When tampering occurs, the terminal reacts:
•
The crypto processor deletes sensitive data
•
A message is displayed to alert the user
•
The crypto processor locks
•
The keypad locks with display of the message, "unauthorized" or "irruption"
•
The damaged security labels provide evidence that the product has been opened.
1.8.2.4
Software design
Software loading is made secure. Only
authentic, signed and certified software
can be loaded into the
terminal.
a) The software identification scheme is based on:
−
Asymmetric encryption algorithm with public and private keys
−
Certified
RSA
cards
−
Software Signature Tool (SST)
b) Software intended to be loaded into the secure terminal must first be signed by a Software Signature Tool
(SST).
They can then be downloaded using an LLT (Local Loading Tool).
c) Once the software is loaded, the
crypto processor checks
the loaded software's certificate and
signature. This operation constitutes the authentication. If the loaded software is authentic, it is accepted.
If this condition is satisfied, the downloading of software into an NBS5XXX using an LLT or a TMS operates
the same way as for other products in SAGEM Monetel's EFT range.
NOTE: "LLT" and "TMS" are described in the section "Loading software".
