A reconciliation approach to key generation based on Module-LWE

2020 · arXiv (Cornell University)

We consider a key encapsulation mechanism (KEM) based on Module-LWE where reconciliation is performed on the 8-dimensional lattice $E_8$, which admits a fast CVP algorithm. Our scheme generates 256 bits of key and requires 3 …

Quantum algorithmic solutions to the shortest vector problem on simulated coherent Ising machines

2023 · arXiv (Cornell University)

Quantum computing poses a threat to contemporary cryptosystems, with advances to a state in which it will cause problems predicted for the next few decades. Many of the proposed cryptosystems designed to be quantum-secure are …
