## Heatmap: Byte Analysis ### Overview The heatmap displays the timing measurements for different byte values, categorized by the guess made by an algorithm. Each row represents a byte, and the columns represent different guesses. The color intensity indicates the timing value, with darker shades representing higher values. ### Components/Axes - **X-axis**: Byte values (0 to 5) - **Y-axis**: Guesses (cookie=0 to cookie=SECRETZ) - **Color Scale**: Darker shades indicate higher timing values ### Detailed Analysis or ### Content Details - **Byte 0**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. - **Byte 1**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. - **Byte 2**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. - **Byte 3**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. - **Byte 4**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. - **Byte 5**: The guess cookie=0 has the highest timing value, followed by cookie=1, cookie=2, and so on. ### Key Observations - **Byte 0**: The guess cookie=0 consistently has the highest timing value across all guesses. - **Byte 1**: The guess cookie=0 consistently has the highest timing value across all guesses. - **Byte 2**: The guess cookie=0 consistently has the highest timing value across all guesses. - **Byte 3**: The guess cookie=0 consistently has the highest timing value across all guesses. - **Byte 4**: The guess cookie=0 consistently has the highest timing value across all guesses. - **Byte 5**: The guess cookie=0 consistently has the highest timing value across all guesses. ### Interpretation The heatmap suggests that the algorithm guesses cookie=0 for all byte values, resulting in the highest timing values. This indicates that the algorithm is likely not correctly identifying the byte values, as the guess cookie=0 consistently results in the highest timing. The other guesses (cookie=1 to cookie=SECRETZ) have lower timing values, suggesting that they are more accurate guesses. However, the algorithm's performance is significantly poor, as it consistently guesses the wrong byte value.
