Abstract

fetched live from OpenAlex

Power analysis is used to reveal the secret key of security devices by monitoring the power consumption of certain cryptographic algorithm operations through a statistical analysis approach known as Differential Power Analysis (DPA). Whilst this has been applied extensively to attacks on FPGA devices, there has been little research into attacks on ASIC devices. Although standard DPAs are essentially independent of the block cipher that they target, some are less susceptible than others due to algorithm's structure, and therefore more difficult to attack such as the CAST-128. In this paper, we outline the first reported power analysis attack of CAST-128 as it falls into the category just outlined and it is the only algorithm that has not been practically broken either on FPGA or ASIC, it is also a common block cipher used in Canada. The paper outlines an approach that reveals all 128 bits of the secret key within 300,500 power traces, highlighting insights on attacking the registers rather than the Sbox. Finally, the effect of applying the Hamming weight power model on different widths of the target register under attack in ASIC device is evaluated.

Full frame distilled prediction

Teacher imitation

Not 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.
