Abstract
The National Institute of Standards and Technology (NIST) in the U.S. has initiated a process to develop an Advanced Encryption Standard (AES) specifying a private-key encryption algorithm based on a 128-bit block size as a replacement for the Data Encryption Standard (DES). We investigate the efficiency of two AES candidates, RC6 and CAST-256, from the hardware implementation perspective with field programmable gate arrays (FPGAs) as the target technology. Our analysis and synthesis studies of the ciphers suggest that it would be desirable for FPGA implementations to have a simpler cipher design that makes use of simpler operations that not only possess good cryptographic properties, but also make the overall cipher design efficient from the hardware implementation perspective.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
