Buffalo built up a 24–10 second half lead and held off an Indianapolis fourth quarter rally to earn their first playoff win since the 1995 season. In the first quarter, Colts quarterback Philip Rivers made completions to T. Y. Hilton and Michael Pittman Jr. for gains of 23 and 22 yards that set up the first score on a 30-yard field goal by Rodrigo Blankenship. Buffalo responded with .

Over the years, PUFs have been widely used in smartcards to provide "silicon .Optical PUFs rely on a random optical multiple-scattering medium, which serves as a token. Optical PUFs offer a promising approach to developing entity authentication schemes that are robust against many of the aforementioned attacks. However, their security against emulation attacks can be ensured only in the case of quantum readout (see below), or when the database of challenge-response pairs is somehow encrypted.
Based on these features, we implement a lens-free, optical, and portable PUF (LOP-PUF) module by optimizing the distance between a silk PUF-tag and an image sensor.
Over the years, PUFs have been widely used in smartcards to provide "silicon fingerprints" as a means of uniquely identifying cardholders based on a challenge-response authentication scheme. The newly proposed method from GIST employs native silk fibers produced by silkworms to create PUF-based tags that are then used to devise a PUF module.
Optical PUFs rely on a random optical multiple-scattering medium, which serves as a token. [10] Optical PUFs offer a promising approach to developing entity authentication schemes that are robust against many of the aforementioned attacks. The UICC smart cards or SIM cards consist of CPU, ROM, SRAM, non-volatile memory like EEPROM, and the ISO/IEC 7816 interface. The USIM cards are intended to securely store the user and the network information within the device. Integrated circuit anti-counterfeiting based on optical physical unclonable functions (PUFs) plays a crucial role in guaranteeing secure identification and authentication for Internet of Things.
A single optical PUF can produce multiple result values by manipulating the optic axis, providing an alternative to diverse data such as fingerprints and iris recognition. Based on these features, we implement a lens-free, optical, and portable PUF (LOP-PUF) module by optimizing the distance between a silk PUF-tag and an image sensor. This simple apparatus easily forms random light-spot patterns with a high-intensity contrast.
A physical unclonable function (PUF) is a physical feature that takes advantage of microscopic differences in electronics to create unique security “keys.”
Herein, a supersaturated solution-based PUF (S-PUF) is presented that utilizes stochastic crystallization of a supersaturated sodium acetate solution to allow a time-efficient, hierarchical authentication process together with on-demand rewritability of cryptographic keys.Similar to the conventional optical PUF, the S-PUF relies on the random speckle pattern I(x, y) generated from the interference between the laser rays that propagate through the grains of sodium acetate crystals created in a stochastic manner.
