Quantum computing is moving from theory to reality. MIT and commercial entities including IBM, Microsoft, and Google have already delivered elementary quantum computing platforms. When large-enough quantum computers are built, known algorithms will be able to weaken or break most of the public-key methods now in use. Concerns over the security threat this represents are growing. To address this, the National Institute of Standards and Technology (NIST) has initiated a process to solicit, evaluate and standardize quantum-resistant, public key, cryptographic methods. In response to NIST’s call for solutions, SecureRF has submitted WalnutDSA, a group-theoretic digital signature method that is resistant to all known quantum attacks.
