I've done a mistake posting 3 thread in the same place
But i've done some researches on that
i know that a titanium card contains a Atmel at90sc3232c
But i can't find a disassembler for this microcontroller
and even if i find i can maybe disassemble the os but not the hex or bin file of seca for exemple
so i want to understand how the os and the bin files works to decrypt seca
my goal is to try to copy the same algorithm on a pic 16f87 card but with a cristal on the card so as to run the microcontroller at a high speed (16mhz for exemple)
