Trusting the algorithms is not a black and white issue. Given that we cannot unequivocally prove the hardness of the problems underlying basic cryptographic primitives, we have no choice but to assume...

The second question my students have asked me about PQ/Classical Hybrids is about why we think they are good for protecting information with a long security lifetime. If we don't trust current PQ...
