Patent number: 10396974Abstract: An apparatus includes signal control circuitry, a phase-locked loop (PLL), and a correlation circuit. The signal control circuitry provides a reference clock signal carrying pseudo-random phase noise and as derived from an application clock signal and pseudo-random noise. The PLL, responsive to the reference clock signal carrying the pseudo-random phase noise, provides an output signal that is related to the phase of the reference clock signal. The correlation circuit self-tests the PLL by cross-correlating a signal corresponding to the output signal from the phase detector with the pseudo-random noise and, in response, by assessing results of the cross-correlation relative to a known threshold indicative of a performance level of the PLL.Type: GrantFiled: July 20, 2018Date of Patent: August 27, 2019Assignee: NXP B.V.Inventors: Jan-Peter Schat, Ulrich Moehlmann

Patent number: 10389517Abstract: A method for performing a secure function in a data processing system is provided. In accordance with one embodiment, the method includes generating and encoding an encryption key. The encoded encryption key may be encrypted in a key store in a trusted execution environment (TEE) of the data processing system. The encrypted encryption key may encrypted, stored, and decrypted in the key store in the TEE, but used in a white-box implementation to perform a secure function. The secure function may include encrypting a value in the white-box implementation for securing a monetary value on, for example, a smart card. In one embodiment, each time an encryption key or decryption key is used, it is changed to a new key. The method makes code lifting and rollback attacks more difficult for an attacker because the key is stored separately from, for example, a white-box implementation in secure storage.Type: GrantFiled: June 27, 2016Date of Patent: August 20, 2019Assignee: NXP B.V.Inventors: Wilhelmus Petrus Adrianus Johannus Michiels, Jan Hoogerbrugge, Joppe Willem Bos

Patent number: 10390440Abstract: In a die-substrate assembly, a copper inter-component joint is formed by bonding corresponding copper interconnect structures together directly, without using solder. The copper interconnect structures have distal layers of (111) crystalline copper that enable them to bond together at a relatively low temperature (e.g., below 300° C.) compared to the relatively high melting point (about 1085° C.) for the bulk copper of the rest of the interconnect structures. By avoiding the use of solder, the resulting inter-component joint will not suffer from the adverse IMC/EM effects of conventional, solder-based joints. The distal surfaces of the interconnect structures may be curved (e.g., one concave and the other convex) to facilitate mating the two structures and improve the reliability of the physical contact between the two interconnect structures. The bonding may be achieved using directed microwave radiation and microwave-sensitive flux, instead of uniform heating.Type: GrantFiled: February 1, 2018Date of Patent: August 20, 2019Assignee: NXP B.V.Inventors: Tsung Nan Lo, Chung Hsiung Ho
