20110154043 | SYSTEMS AND METHODS FOR CRYPTOGRAPHICALLY ENHANCED AUTOMATIC BLACKLIST MANAGEMENT AND ENFORCEMENT - Embodiments relate to systems and methods for the management and enforcement of blacklists of counterfeited, cloned or otherwise unauthenticated devices. In an embodiment, a system comprises an accessory comprising an authentication chip including data signed by a private verification key, the data including a unique identifier related to the accessory, and a device comprising a public verification key forming a verification key pair with the private verification key and an identifier list, the device configured to read the data from the authentication chip, compare the unique identifier with the identifier list, and reject the accessory if the unique identifier is found in the identifier list. | 06-23-2011 |
20120213361 | SYSTEMS AND METHODS FOR DEVICE AND DATA AUTHENTICATION - Embodiments relate to systems and methods for authenticating devices and securing data. In embodiments, a session key for securing data between two devices can be derived as a byproduct of a challenge-response protocol for authenticating one or both of the devices. | 08-23-2012 |
20130043878 | COMMUNICATION LINE DRIVER PROTECTION CIRCUITRY, SYSTEMS AND METHODS - Embodiments relate to fault detection comparator circuitry and methods that can operate in conjunction with a power-on-reset (POR) scheme to put a chip into a reliable power-down mode upon fault detection to avoid disrupting the communication bus link such that other connected chips and the host can continue to operate. Power-on of the affected chip can then be carried out when the connection with that chip is restored. | 02-21-2013 |
20130222109 | System-Level Chip Identify Verification (Locking) Method with Authentication Chip - A system for authenticating electronic devices, particularly chips or integrated circuits is described. This allows authenticating that the devices are authorized by the original manufacturer for operation in critical applications. | 08-29-2013 |
20140013171 | INTEGRATED DEFECT DETECTION AND LOCATION SYSTEMS AND METHODS IN SEMICONDUCTOR CHIP DEVICES - Embodiments relate to systems and methods for defect detection and localization in semiconductor chips. In an embodiment, a plurality of registers is arranged in a semiconductor chip. The particular number of registers can vary according to a desired level of localization, and the plurality of registers are geometrically distributed such that defect detection and localization over the entire chip area or a desired chip area, such as a central active region, is achieved in embodiments. In operation, a defect detection and localization routine can be run in parallel with other normal chip functions during a power-up or other phase. In embodiments, the registers can be multi-functional in that they can be used for other operational functions of the chip when not used for defect detection and localization, and vice-versa. Embodiments thereby provide fast, localized defect detection. | 01-09-2014 |
20140129837 | SYSTEMS AND METHODS FOR DEVICE AND DATA AUTHENTICATION - Embodiments relate to systems and methods for authenticating devices and securing data. In embodiments, a session key for securing data between two devices can be derived as a byproduct of a challenge-response protocol for authenticating one or both of the devices. | 05-08-2014 |
20140129840 | SYSTEMS AND METHODS FOR DEVICE AND DATA AUTHENTICATION - Embodiments relate to systems and methods for authenticating devices and securing data. In embodiments, a session key for securing data between two devices can be derived as a byproduct of a challenge-response protocol for authenticating one or both of the devices. | 05-08-2014 |
20150162828 | RECONFIGURABLE MULTIPHASE POWER STAGE FOR SWITCHED MODE CHARGERS - Methods, devices, and integrated circuits are disclosed for providing a buck converter charger in a multiphase buck converter topology comprising at least a first phase, a second phase, and an alternative charging switch, wherein the first phase includes a first high-side switch and a first low-side switch and the second phase includes a second high-side switch and a second low-side switch. The methods, devices, and integrated circuits may control at least one phase to operate as a boost converter, control at least one phase to operate as buck converter, and close the alternative charging switch in the multiphase buck converter topology to connect an alternative charging source to a system voltage output, the alternative charging switch coupled to the first phase between the first high-side switch and the first low-side switch. | 06-11-2015 |
