The Exact Security of PMAC by Peter Gaži, Krzysztof Pietrzak, Michal Rybár

“…In the PMAC construction one initially XORs a mask to every message block, where the mask for the ith block is computed as τi := γi·L, where L is a (secret) random value, and γi is the i-th codeword of the Gray code. Our attack applies more generally to any sequence of γi’s which contains a large coset of a subgroup of GF(2n). …”

Towards efficient 3D calibration for different types of multi-view autostereoscopic 3D displays by Xia, Xinxing, Guan, Yunqing, State, Andrei, Cham, Tat-Jen, Fuchs, Henry

“…In our method, a camera is placed at different locations within the viewing volume of a 3D display to capture a series of images that relate to the subset of light rays emitted by the 3D display and arriving at each of the camera positions. Gray code patterns modulate the images shown on the 3D display, helping to significantly reduce the number of images captured by the camera and thereby accelerate the process of calculating the correspondence relationship between the pixels on the 3D display and the locations of the capturing camera. …”
