Abstract (en)

[origin: EP0762338A2] A summation is used for a starting check (1020) in the frame of the starting and initialisation routine (101) that runs before the printed date routine (1040) and the following system routine (200) for validating the programme code and certain data. The appropriate MAC is entered and the above routine is performed using a summation testing method from the OTP processor, with its algorithm and key. The franking machine is run in the same routine (200) of a similar validation is made, and the process is repeated for various manipulation or handling modes.
