Patent number: 10945051Abstract: An apparatus includes a processor that monitors transmissions destined for an external network, determines that a transmission includes original media associated with a subject, and intercepts the transmission before it reaches the external network. The processor generates modified media by selecting a subset of data elements of the original media and replacing a value of each data element of the subset with a new value. At least one of the subset of data elements and the set of new values is chosen such that an accuracy metric calculated for a first generative algorithm, trained to generate synthetic representations of the subject based on modified media, is less than, by a given factor, the accuracy metric calculated for a second generative algorithm, trained to generate synthetic representations of the subject based on original media. The processor replaces the transmission with a new transmission that includes the modified media.Type: GrantFiled: April 6, 2020Date of Patent: March 9, 2021Assignee: Bank of America CorporationInventors: Matthew Bruce Murray, Garrett Thomas Botkin, Kathleen D.

Patent number: 10680810Abstract: A method is provided for generating an elliptic curve cryptography key pair that uses two topologically identical pseudo-random number generators operating in parallel and in step with each other. One generator operates in the scalar number domain and the other generator operates in the elliptic curve point domain. Parallel sequences of pseudo-random elliptic curve points aG and corresponding scalars a are generated in this manner. A scalar a becomes a private key and an elliptic curve point aG is a public key of a key pair. Each generator is advanced by one iteration successively, and the isomorphic relationship ensures that the point domain generator always contains values which are multiples of the system base point according to values contained in the corresponding position in the number domain generator. In one embodiment, the pseudo-random number generators are each characterized as being lagged Fibonacci generators.Type: GrantFiled: October 26, 2016Date of Patent: June 9, 2020Assignee: NXP B.V.Inventors: Joppe Willem Bos, Bjorn Fay, Bruce Murray

Patent number: 10437524Abstract: In high security devices, like smart cards, the on-board software may be embedded in ROM (read only memory). But, based on flexibility arguments, non-volatile flash memory based software storage can be more preferred. This invention describes a method to recover from a situation of data loss on flash devices by combining the on-device available secure boot-loading with embedded physical unclonable functions (PUF), where the PUF provides the cryptographic key for starting the data recovery procedure.Type: GrantFiled: October 12, 2017Date of Patent: October 8, 2019Assignee: NXP B.V.Inventors: Thomas Wille, Bruce Murray

Publication number: 20190249081Abstract: Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape).Type: ApplicationFiled: April 26, 2019Publication date: August 15, 2019Applicants: INTELLIGENT MATERIAL SOLUTIONS, INC., THE TRUSTEES OF THE UNIVERSITY OF PENNSYLVANIAInventors: Joshua E.

Patent number: 10341098Abstract: A method is provided for performing elliptic curve cryptography that reduces the number of required computations to produce, for example, a key pair. The number of computations is reduced by changing how a random nonce used in the computations is selected. In an embodiment, a look-up table is generated having pre-computed scalar values and elliptic curve points. Every time a new pseudo-random value is created for use in the ECDSA, a combination of the look-up table values is used to create multiple intermediate values. One of the multiple intermediate values is randomly chosen as a replacement value for one of the existing table entries. Each time the look-up table is used, multiple entries in the look-up table are updated to new look-up table values as described. In this manner, new randomness is provided in every step to generate the next pseudo-random nonce as a combination of multiple internally stored temporary look-up table values. Alternately, another mathematical group may be used.Type: GrantFiled: January 24, 2017Date of Patent: July 2, 2019Assignee: NXP B.V.Inventors: Joppe Willem Bos, Bjorn Fay, Bruce Murray

Patent number: 10146464Abstract: A data processing system having a PUF and method for providing multiple enrollments, or instantiations, of the PUF are provided. A PUF segment includes a plurality of SRAM cells on an integrated circuit. A PUF response from the PUF segment is used to create a first activation code and a first PUF key. A second PUF key may be created from the PUF response. Initially, during a second enrollment, the PUF response is combined with the first activation code to reproduce a codeword. The first secret string is reconstructed by encoding the codeword. The codeword is combined with the first activation code to reproduce the PUF response. Inverse anti-aging is applied to the PUF response. Then a second secret string is generated using a random number generator (RNG). The second secret string is encoded to produce a new codeword. The new codeword is combined with the recovered PUF response to create a second activation code. The second activation coded is hashed with the second secret string to provide a second PUF key.Type: GrantFiled: June 30, 2016Date of Patent: December 4, 2018Assignee: NXP B.V.Inventors: Bruce Murray, Helmut Alexander Goettl, Sven Heine, Christiaan Kuipers
