  • Publication number: 20220197982
    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.

  • Patent number: 10740497
    Abstract: A method is disclosed for providing first data and a first secret key to a cipher processor for ciphering. The first data is ciphered in accordance with a first cipher process and the first secret key to provide output data. Before ciphering of the first data, extra data is inserted within the cipher processor for ciphering in accordance with at least a portion of said first cipher process. The extra data is inserted within a sequence of cipher processor operations for obfuscating the output data.

  • Patent number: 10244428
    Abstract: The invention relates to the field of data packet management, and more specifically to the field of managing of data packets in such a manner that power consumption is reduced, such reduction being especially beneficial for portable device applications. In accordance with an embodiment of the invention there is provided a method of handling and manipulating data wherein padding and unpadding operations for a packet of data are performed at the transmission/reception of a packet from a network, and data handling is minimized within the portable device. According to another embodiment of the invention there is provided a method of encryption for packet data absent the padding data.

  • Patent number: 9900149
    Abstract: A method of improving the efficiency of an encryption/decryption process implementing the NIST FIPS 197 standard which includes a substitution box (S-box) and an inverse substitution (inverse S-box), comprises concatenating the S-box and inverse S-box to form a combined lookup table, and folding the concatenated table to generate a folded lookup table. The folded lookup table may be indexed for an encryption operation and for a decryption operation using a signal indicative of whether encryption or decryption is used.
