Mechanism To Authenticate A Reader To A Credential, David Mercer, Steve Paik, Ross Hewit

Defensive Publications Series

Access to data objects stored on a credential such as a badge, smart card, etc. is typically limited to user authorization through the use of a user-entered PIN or other mechanism. This disclosure describes techniques to enable a credential reader to authenticate itself to a credential and access protected objects on the credential without user interaction and without the use of any global credential. The techniques define a simplified public-key infrastructure (PKI) hierarchy appropriate for typical credentials, which are usually low-powered, passive, and offline.

Transferring Credentials Between Devices, David Mercer, Steve Paik, Ross Hewit

Defensive Publications Series

A badge user may want to use a different device, e.g., a smartphone, a smartwatch, etc., as their credential in lieu of the badge. This disclosure describes techniques to securely transfer credentials from a first device (e.g., badge) to a second device (e.g., phone) such that only one device with valid credentials exists at any time. Per the techniques, the two devices perform a cryptographic transfer to move credentials, and the credentials on the first device are destroyed. In this manner, only one credential at a time can be authenticated for the user. The techniques can operate offline, e.g., with …

Data Object Extensions For Access Control Credentials, David Mercer, Steve Paik, Ross Hewit

Defensive Publications Series

Traditional access control credentials require authentication against a backend and have no mechanism to work offline. Also, traditional credentials such as badges typically have a photo to identify the credential holder. The forgery of the outward appearance of a credential to the extent that it will pass a visual inspection is easily possible, even when modern anti-forgery techniques are employed. This disclosure describes techniques that extend security credentials to provide secure, authenticated, offline access. An authorized person can validate a badge or other credential by tapping it against an authenticated credential reader. Data on the credential is containerized such that …

Defensive Publications Series

Application programming interfaces (APIs) are becoming increasingly prevalent across the industry. At its heart, an API is a means for transferring data between two systems in an interoperable way. While the data that is passed across an API is generally well structured, that structure can be arbitrarily complex. Determining whether or not a set of data is valid is often not straightforward, as there may be complex dependencies between different data items in a set. Writing custom code to perform such a validation is time consuming and prone to error. To address challenges of these types, techniques are presented herein …

Self-Tilting Wing For Vtol And Ctol, Colin Hilton

Defensive Publications Series

‘Free’ wings deflected by a combination of free-stream airflow and servo-tab deflection date back to the 1940s, but may be applied with especial relevance in combination with tilt-wing forms of electrical vertical take-off and landing (eVTOL). An advantage of the means described is that forward impetus alone initiates a transition from a vertical-oriented airfoil to forward-oriented. Although this might use a separate power means, the device allows for a simple quadcopter to take off or land vertically as well as induce forward flight, purely by conventional quadcopter control.

Processing-In-Memory For Weight Updates In A Neural Network Accelerator, N/A

Defensive Publications Series

Leveraging the vectorizability of deep-learning weight-updates, this disclosure describes processing-in-memory (PIM) techniques for weight-updates in a large class of deep learning networks. Rather than importing the state of the deep-learning optimizers to the computational die, the techniques send gradients to a die of a high-bandwidth memory (HBM) stack and perform the modest number of optimizer updates in compute units located in the die. Since reads and writes are done inside the HBM stack, the techniques can substantially reduce the CPU-HBM bandwidth requirements. Weight-related memory traffic, dominant for multilayer perceptrons and transformers, is also reduced.
