Crack MICROCONTROLLER Protection Method

Crack MICROCONTROLLER Protection Method

 

Crack MICROCONTROLLER is a prevail technology in the industry of Electronic Product Reverse Engineering, Relevant protection mechanism has been established to protect MICROCONTROLLER Crack in the world. Asynchronous logic is a recently developed Crack MICROCONTROLLER protection technology, it has been introduced after the synchronous dual line logic promotion. As we all know, traditional digital logic use only one clock to synchronize the operation when Crack MICROCONTROLLER. But accompany with acceleration of clock rate, this synchronized operation becomes more and more complicate. Due to this reason, it give rise to the self-synchronized or asynchronous design without the clock. There is one way is to use random technology on the data line to prevent Crack MICROCONTROLLER, in the dual line logic, signal zero and one is not high and low electrical press on single line anymore, but a pair of signal combination on the line. Such as zero could probably LH, while one is probably HL, when in the application of synchronous circuit, LL signal means motionless when Crack MICROCONTROLLER. The main drawback of all these simple arrangement is they are very fragile: un-wanted HH status could emerge due to the circuit disadvantage when Crack MICROCONTROLLER.

Self-asynchronous design can be used to fend off the clock noise MICROCONTROLLER cracking. If the serial interface need clock, it is relatively easier to separate the clock from sensitive circuit. Power supply noise MICROCONTROLLER crack can seldom work on the asynchronous circuit, however, for those MICROCONTROLLER with eeprom as memorizer won’t be protected and could be cracked.

Dual Line design can obtain the alerting signals from sensor modification reliably, and constrain the operation of MICROCONTROLLER. The final result could be the deletion of sensitive data from MICROCONTROLLER and trigger the alert, it can prevent the flaw injection MICROCONTROLLER crack to gain success, MICROCONTROLLER cracker should inject two failure status simultaneously and make the status of transmitting line from LH switch to HL, which can cause the transmitting status enter into HH immediately and trigger the alert right away.
