Randomized Key Encapsulation/Consolidation. (arXiv:2401.16993v1 [cs.CR])

This article bridges the gap between two topics used in sharing an encryption
key: (i) Key Consolidation, i.e., extracting two identical strings of bits from
two information sources with similarities (common randomness). (ii)
Quantum-safe Key Encapsulation by incorporating randomness in Public/Private
Key pairs. In the context of Key Consolidation, the proposed scheme adds to the
complexity Eve faces in extracting useful data from leaked information. In this
context, it is applied to the method proposed in [1] for establishing common …
