run sagemath script
deactivate the venv first, then with sagemath installed:
./run_sage.sh
Modes are:
| Mode | Explanation |
|---|---|
| 1. Classic inspection | run n steps |
| 2. Advanced inspection with forced 0 or 1 bits | run n steps but with bits forced to 0 or 1 |
| 3. Exhaustive variable-change search | - |
| 4. S box analysis | - |
| 5. Variable XOR | XOR chosen bits inside a register and check the evolution during n steps |
| 6. F31, F32 analysis | - |
| 7. Exhaustive XOR search | XOR bits inside a register, returns the best combination (least number of monomials) |
| 8. Cube attack search | offline part of the cube attack (a precomputed model can be used) |
| 9. Precompute and save model | precompute n steps and save the model |
| 10. Load model | load a saved model |
n steps can be precomputed and then loaded for the offline part of the cube attack with the menu entries 9 and 10.
