Investigation of Some Attacks on GAGE (v1), InGAGE (v1), (v1.03), and CiliPadi (v1) Variants
In this paper, we present some attacks on GAGE, InGAGE, and CiliPadi which are candidates of the first round of the NIST-LWC competition. GAGE and InGAGE are lightweight sponge based hash function and Authenticated Encryption with Associated Data (AEAD), respectively and support different sets of parameters. The length of hash, key, and tag are always 256, 128, and 128 bits, respec...
متن کاملMagnetoencephalographic investigation of human cortical area V1 using color stimuli.
The aim of this study was to determine the response properties of the human visual cortex to chromatic stimuli using magnetoencephalography (MEG). Evoked responses were recorded to isoluminant red/green sinusoidal gratings for a wide range of spatial and temporal frequencies. For each condition the response was dominated by a single major component which was well modeled by an equivalent curren...
متن کاملResponse profiles to texture border patterns in area V1.
Cells in area V1 of the anesthetized macaque monkey were stimulated with large texture patterns composed of homogeneous regions of line elements (texels) with different orientations. To human observers, such patterns appear to segregate, with the percept of sharp boundaries between texture regions. Our objective was to investigate whether the boundaries are reflected in the responses of single ...
متن کاملActivation of human extrageniculostriate pathways after damage to area V1.
We have used positron emission tomography (PET) to specify the cortical and subcortical structures activated following visual stimulation of the scotomatous field in a patient with an asymmetric bilateral developmental anomaly of the visual cortex. Computerized perimetry indicated a left visual field defect only although MRI and 18FDG-PET scans showed abnormalities in both occipital lobes. The ...
متن کاملSpatial frequency and orientation tuning dynamics in area V1.
Spatial frequency (SF) and orientation tuning are intrinsic properties of neurons in primary visual cortex (area V1). To investigate the neural mechanisms mediating selectivity in the awake animal, we measured the temporal dynamics of SF and orientation tuning. We adapted a high-speed reverse-correlation method previously used to characterize orientation tuning dynamics in anesthetized animals ...
