Abstract:
A method for chip encryption includes obtaining a fuse value and a trim value of a chip and setting an encryption algorithm, setting the fuse value and the trim value as parameters of the encryption algorithm and obtaining a secret key which is unique for the chip accordingly to the encryption algorithm, and storing the fuse value, the trim value and the secret key in the chip. Since the fuse value and trim value of the chip are unique naturally, the secret key obtained from the same matrix chip for different applications or different matrix chips for the same application are different from each other, thereby increasing expenses and difficulty for crackers to crack the chip and protecting user's intellectual property perfectly.

Claim (Index 18):
The method for chip encryption as claimed in  claim 3 , wherein the trim value of the chip is unique.
