    Abstract: Some aspects of this disclosure are directed to implementing hardware-based obfuscation of digital data. For example, some aspects of this disclosure relate to a method, including performing a capture operation that loads a plurality of primary input (PI) bits into corresponding shift registers of a plurality of test data registers (TDRs) disposed on one or more digital semiconductor devices and configured to store a plurality of secret information bits. The method further includes performing a sequence of shift operations on the plurality of TDRs to obtain a plurality of output bits. The method further includes applying, by an authenticating processor, a derivation function on the plurality of output bits to extract the plurality of secret information bits thereby authenticating the one or more digital semiconductor devices.
