After this module you can
- Explain what a lattice problem is and why it resists Shor
- Explain why hash-based and code-based approaches offer a different trust model from lattices
Before thisM1: The quantum threat
- 01Lattice and LWE intuitionFOUNDATIONS: state in one sentence what a lattice problem is and why it resists Shor's algorithm
- 02Hash-based and code-based intuitionExplain what 'stateful' means for hash-based signatures (SLH-DSA, LMS, XMSS) and why security collapses completely if key state is reused
