    摘要: Physical Unclonable Functions (PUFs) for authentication can be implemented in a variety of electronic devices including FPGAs, RFIDs, and ASICs. In some implementations, challenge-response pairs corresponding to individual PUFs can be enrolled and used to determine authentication data, which may be managed in a database. Later when a target object with a PUF is intended to be authenticated a set (or subset) of challenges are applied to each PUF device to authenticate it and thus distinguish it from others. In some examples, authentication is achieved without requiring complex cryptography circuitry implemented on the device. Furthermore, an authentication station does not necessarily have to be in communication with an authority holding the authentication data when a particular device is to be authenticated.

    摘要: Systems and methods for communication between local wireless networks and mobile devices and more particularly, to sending presence-based content to mobile devices over local wireless network access points. The method includes receiving notification that the mobile device has established a wireless network connection with a LWN through a WAP of the LWN; receiving a request from a content provider to send content through the WAP to the mobile device; allowing the content provider to send content to the mobile device through the WAP or other network connected to the mobile device. In one exemplary method, a wireless service provider or mobile device user can govern what content is sent to a mobile device.

    摘要: 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.
