MinimaxComp_degrees This algorithm finds optimized degrees for comparison/max/ReLU algorithms using minimax composite polynomial on the RNS-CKKS scheme, which was proposed in https://ieeexplore.ieee.org/document/9517029 and https://eprint.iacr.org/2021/1215 . How to run on macOS using the Apple Clang compiler: 1. % brew install NTL 2. % export LIBRARY_PATH=/usr/local/lib 3. % git clone  https://github.com/eslee3209/MinimaxComp_degrees 4. % cd MinimaxComp_degrees 5. % cmake -S . -B build 6. % cd build 7. % make 8. % ./degrees Output: ------------------------------------ alpha: 20 epsilon: 0.2002716064453125e-4 mintime: 162 depth: 22 0.39825903512705770933e-4 7 13 15 15 59   This guide runs MinimaxComp_degrees on macOS, an algorithm that finds optimized polynomial degrees for comparison, max, and ReLU operations under the RNS-CKKS homomorphic encryption scheme, based on the referenced research. CKKS can only evaluate polynomials on encrypted data, so non-polyn...

CRC RevEng CRC RevEng is a portable, arbitrary-precision CRC calculator and algorithm finder. It calculates CRCs using any 111 preset algorithms or a user-specified algorithm to any width. It calculates reversed CRCs to give the bit pattern that produces a desired forward CRC. CRC RevEng also reverse-engineers any CRC algorithm from good, correctly formatted message-CRC pairs and optional known parameters. It comprises powerful input interpretation options. Installation instructions for macOS: 1. Download reveng from SourceForge:  https://sourceforge.net/projects/reveng/files/ 2. Unzip the downloaded reveng zip file 3. % cd Downloads/reveng-3.0.3 4. % make gcc -O3 -Wall -ansi -fomit-frame-pointer -DPRESETS -DBMPTST -o bmptst bmpbit.c ( ./bmptst && touch bmptst ) || ( rm bmptst bmptst.exe && false ) reveng: configuration fault.   Update config.h with these definitions and recompile: #define BMP_BIT   64 #define BMP_SUB   32 rm: bmptst.exe: No suc...

Code: all_results = all_results.append(current_result) Error: /var/folders/wh/tdg0ff9s1wl59234d5l27_gc0000gn/T/ipykernel_98654/2691205834.py:15: FutureWarning: The frame.append method is deprecated and will be removed from pandas in a future version. Use pandas.concat instead. all_results = all_results.append(current_result) Fix: all_results = pd.concat([all_results, current_result]) This warning appears because DataFrame.append was deprecated and later removed from pandas, so code that built a frame by appending one row or frame at a time needs updating. The replacement is pandas.concat, which combines a list of frames in one call. Collecting the pieces in a list and concatenating once at the end is also faster than repeated appends.

Code: ax = sns.swarmplot(y="time_taken", x="dtype", data=all_results, color=".25") Error: /usr/local/Cellar/jupyterlab/3.3.2/libexec/lib/python3.9/site-packages/seaborn/categorical.py:1296: UserWarning: 35.9% of the points cannot be placed; you may want to decrease the size of the markers or use stripplot. warnings.warn(msg, UserWarning) Fix: ax = sns.swarmplot(y="time_taken", x="dtype", data=all_results, color=".25", size=3.25 ) This seaborn warning appears when a swarm plot cannot place every point without overlap, so some are dropped. It is a sign the markers are too large for the amount of data. Reducing the marker size with the size parameter, or switching to a strip plot, lets all points show. Both are quick changes to the plotting call.
