Abstract: An authentication model dynamically adjusts authentication factors required for access to a remote resource based on changes to a risk score for a user, a device, or some combination of these. For example, the authentication model may conditionally specify the number and type of authentication factors required by a user/device pair, and may dynamically alter authentication requirements based on changes to a current risk assessment for the user/device while the remote resource is in use.

Abstract: A design for test focused tester has a single printed circuit board tester architecture. By focusing on design for test testing and eliminating functional testing, the design for test focused tester reduces or eliminates requirements for high speed, precision signal formatting and timing circuitry that require a multiple board architecture interconnected via a high speed backplane. The single board architecture places a vector sequencer and vector memory close to the device under test, which provides short, consistent signal paths to the device and eliminates the need for dead cycles and synchronization between tester boards.

Abstract: A scan test viewing and analysis tool for an integrated circuit tester provides inter-related views of scan tests on an integrated circuit device. The tool processes a test program specification, execution results and device definition to produce cross-referencing data, which the tool then uses to provide navigation links between correlated locations in a cyclized test view, procedural test program view, and views of signal vectors, scan state and scan vectors. The tool also provides a capability to edit the test program in the views.

Abstract: A DFT-focused tester has a single printed circuit board tester architecture. By focusing on DFT testing and eliminating functional testing, the DFT-focused tester reduces or eliminates requirements for high speed, precision signal formatting and timing circuitry that require a multiple board architecture interconnected via a high speed backplane. The single board architecture places a vector sequencer and vector memory close to the device under test, which provides short, consistent signal paths to the device and eliminates the need for dead cycles and synchronization between tester boards.
