Abstract:

   The presence of a Cryptographically Relevant Quantum Computer (CRQC)
   would render state-of-the-art, traditional public-key algorithms
   deployed today obsolete, since the assumptions about the
   intractability of the mathematical problems for these algorithms that
   offer confident levels of security today no longer apply in the
   presence of a CRQC.  This means there is a requirement to update
   protocols and infrastructure to use post-quantum algorithms, which
   are public-key algorithms designed to be secure against CRQCs as well
   as classical computers.  These new public-key algorithms behave
   similarly to previous public key algorithms, however the intractable
   mathematical problems have been carefully chosen so they are hard for
   CRQCs as well as classical computers.  This document explains why
   engineers need to be aware of and understand post-quantum
   cryptography.  It emphasizes the potential impact of CRQCs on current
   cryptographic systems and the need to transition to post-quantum
   algorithms to ensure long-term security.  The most important thing to
   understand is that this transition is not like previous transitions
   from DES to AES or from SHA-1 to SHA-2.  While drop-in replacement
   may be possible in some cases, others will require protocol re-design
   to accommodate significant differences in behavior between the new
   post-quantum algorithms and the classical algorithms that they are
   replacing.
