Abstract: A field configurable device, such as an FPGA, supports secure field configuration without using non-volatile storage for cryptographic keys on the device and without requiring a continuous or ongoing power source to maintain a volatile storage on the device. The approach can be used to secure the configuration data such that it can in general be used on a single or a selected set of devices and/or encryption of the configuration data so that the encrypted configuration data can be exposed without compromising information encoded in the configuration data.

Abstract: A key is determined from a volatile response using circuitry on the device. The volatile response depend on process variation in fabrication of the device. Error control data that depends on the first volatile response can be computed, stored externally to the device, and then used to generate the key using a volatile response using the circuit. Applications of volatile keys include authentication and rights management for content and software.

Abstract: Subsets of multiple signal generator circuits embodied in a device are selected, and then a volatile value for the device is generated from the selected subsets. The volatile value may be used for authentication of the device and/or for cryptographic procedures performed on the device. The signal generator circuits may each comprise an oscillator circuit, and the selection of the subsets may be according to a comparison of the outputs of the subsets of circuits, for example, according to a comparison of output oscillation frequencies.

Abstract: A method for providing access to device-specific information includes providing a first value to the device, and then, in the device, using a second value that is a first one-way function of the provided first value to determine a third value such that the third value is a device-specific function of the second value. The third value is then accepted from the device and stored outside the device. Subsequent to accepting the third value from the device, the second value is provided to the device. In the device, the provided second value is used to determine the third value once again and a fourth value is determined that is a second one-way function of the third value. This determining of the fourth value is performed without disclosing the third value outside the device. The fourth value is accepted from the device.

Abstract: The present invention generally relates to engineered bacteriophages which express amyloid peptides for the modulation (e.g. increase or decrease) of protein aggregates and amyloid formation. In some embodiments, the engineered bacteriophages express anti-amyloid peptides for inhibiting protein aggregation and amyloid formation, which can be useful in the treatment and prevention of and bacterial infections and biofilms. In some embodiments, the engineered bacteriophages express amyloid peptides for promoting amyloid formation, which are useful for increasing amyloid formation such as promoting bacterial biofilms. Other aspects relate to methods to inhibit bacteria biofilms, and methods for the treatment of amyloid related disorders, e.g., Alzheimer's disease using an anti-amyloid peptide engineered bacteriophages. Other aspects of the invention relate to engineered bacteriophages to express the amyloid peptides on the bacteriophage surface and/or secrete the amyloid peptides, e.g., anti-amyloid peptides and pro-amyloid peptides, and uses thereof for modulation protein aggregates and amyloid formation.

Abstract: A device-specific value is reliably generated in a device. In a first component of the device, a first digital value is generated that is substantially dependent fabrication variation among like device. Redundancy information is computed based on the first digital value. A subsequent digital value is later generated in the first component of the device. The first digital value is then determined in a second component of the device from the subsequent digital value and the redundancy information.
