More and more consumer electronic devices are equipped with Nand Flash as nonvolatile memory device. Unique digital fingerprint information can be extracted from each Nand Flash chip by using the physical properties of Nand Flash, which are determined in the production process. We propose a new method, based on the physical properties of Nand Flash, to produce private keys for SM2 signature scheme, which is verifiably tight coupled to the Nand Flash device. Notably, this method is irrelevant to the specific digital signature schemes, and it is applicable to any occasion where digital signature scheme is used for identification of the storage devices or electronic devices.
Key words： Nand Flash; SM2; random number; digital signature
