The invention discloses a method for secure lifecycle tracking information of a microchip using e-fuses, whereas the microchip is identified with a unique key, the lifecycle tracking information is monitored by a counter value of a counter unit and the counter values are stored on the microchip by setting e-fuse bits in e-fuses. The objective of the present invention to provide a method that hinders a physical manipulation of e-fuse based lifecycle counters by attackers will be solved by means of a permutation performed by a deterministic algorithm using the microchip unique key as a random seed, the e-fuse values are shuffled and re-mapped to the counter values, thereby enabling the e-fuse values to be uniquely assigned to the counter values.
