A method for preventing the illegal duplication of an electronic product by using a semiconductor chip set and an apparatus thereof are provided to prevent the firmware hacking of a central processing unit and the hacking performed through the decap of the semiconductor chip set. A developer program(101) generates a public key AP and a secret key AK, and encrypts the generated secret key AK through a secret key encryption algorithm. A central processing unit(102) executes the firmware, operates a public key encryption algorithm, and then finally determines whether a product is duplicated or not. A semiconductor chipset(103) has a flash memory to store the secret key decryption algorithm and public key decryption algorithm.
