Abstract: An engine valve actuation system includes a rotatable camshaft having a cam lobe, and a lifter arm assembly having a lifter arm with a roller in contact with the cam lobe. A bushing is positioned in a pin bore of the lifter arm and journals the lifter arm upon the pin for reciprocation in response to rotation of the camshaft. An incoming oil passage extends to the pin bore, and an outgoing oil passage extends from the pin bore. The outgoing oil passage forms an oil spray port defining an oil spray path oriented to direct a spray of oil at the roller and/or the cam lobe. An oil feed groove is formed in at least one of the lifter arm or the bushing and fluidly connects the incoming oil passage to the outgoing oil passage.

Abstract: A method for generating a secure nonce using a one-time programmable (OTP) memory within an integrated circuit to provide persistence, the method including randomly selecting k currently-unprogrammed bits in the OTP memory, creating a data set using data derived from current contents of the OTP memory altered by changing the states of the k currently-unprogrammed bits of the OTP memory, and employing as the secure nonce the data set or data derived from the data set. The selected k bits are programmed in the OTP memory.

Abstract: A method for controlling the use of intellectual property (IP) in an individual integrated circuit includes loading data including the IP into the individual integrated circuit, loading an IP license certificate into the individual integrated circuit, the certificate including identification of the IP authorized for the individual integrated circuit, determining inside the individual integrated circuit whether the IP is authorized for the individual integrated circuit, enabling operation of the individual integrated circuit if the IP circuit is authorized for use in the individual integrated circuit, and imposing a penalty on operation of the individual integrated circuit if the IP is not authorized for use in the individual integrated circuit.

Abstract: A method for determining if an individual integrated circuit was manufactured using an individual instance of tooling includes collecting from the individual integrated circuit first data representing at least one attribute that varies as a function of the tooling used to manufacture the individual integrated circuit and second data identifying the integrated circuit as having been manufactured using the individual instance of tooling. The first data is compared to a signature of the individual instance of tooling identified by the second data. The signature is derived from the at least one attribute measured from a population of integrated circuits that were manufactured using the individual instance of tooling. The individual integrated circuit is identified as having been manufactured using the individual instance of tooling identified in the second data collected from the individual integrated circuit if the first data correlates to the signature by a predetermined threshold.

Abstract: A method for securely booting a target processor in a target system from a secure root of trust includes computing a message authentication code from boot code to be provided to the target processor, including an obfuscated algorithm for recreating the message authentication code in the target processor, serving the boot code to the target processor, executing the boot code to recreate the message authentication code in the target processor, serving the message authentication code back to the root of trust, comparing the returned message authentication code with the message authentication code generated in the root of trust, continuing execution of the boot code data if the returned message authentication code matches the message authentication code, and applying at least one penalty to the target system if the returned message authentication code does not match the message authentication code generated in the root of trust.
