Leech-FrodoKEM Security Scripts

This dataset contains the source code for our Leech Lattice-based FrodoKEM scheme. The package includes: para_A.ipynb, para_B.ipynb, para_C.ipynb: Scripts for computing parameters at NIST security levels 1, 3, and 5. These generate Tables 3-5 in the paper. para_one.ipynb, para_two.ipynb, para_three.ipynb: Scripts for performance analysis (Table 8). leech_frodokem_simulation.py and .ipynb: Complete protocol simulation showing key generation, encapsulation, decapsulation, and end-to-end key recovery verification. leech_basis.txt: The 24×24 Leech lattice basis matrix. README.txt: Instructions for running the code. All scripts require SageMath 9.3 and can be executed in Jupyter Notebook. The code reproduces the security analysis, DFP bounds, and bandwidth comparisons reported in the manuscript.
