Example flow to load master keys with security:
In the following example we assume a bank receives a new PP791 and wants to initialize it before deploy.
And want to update some master keys after its deployed. We also assume the master key to be loaded is
position 0 and position F; their values are already stored in a Tamper Resistant Security Module (TRSM)
in a secure way.
1. The bank must generate two passwords, and make two authorized people to keep them separately.
2. Authorized people must enter KEY INJECT AUTH menu and change password 1 and password 2.
3. After password changed, connect PIN Pad to TRSM, enter KEY INJECT AUTH menu again and
choose Inject MKEY/IPEK function.
4. Operate TRSM to load master key #F and master key #0.
After step 4 finishes, user can issue other commands to PIN pad (such as message 08 to select key
#0 as active master key) or turn it off and deploy it.
5. To load or update master keys at field site, user should issue encrypted command 02.
