Query: Identifying Research Challenges in Post Quantum Cryptography Migration
  and Cryptographic Agility   The implications of sufficiently large quantum computers for widely used
public-key cryptography is well-documented and increasingly discussed by the
security community. An April 2016 report by the National Institute of Standards
and Technology (NIST), notably, calls out the need for new standards to replace
cryptosystems based on integer factorization and discrete logarithm problems,
which have been shown to be vulnerable to Shor's quantum algorithm for prime
factorization. Specifically, widely used RSA, ECDSA, ECDH, and DSA
cryptosystems will need to be replaced by post-quantum cryptography (PQC)
alternatives (also known as quantum-resistant or quantum-safe cryptography).
Failure to transition before sufficiently powerful quantum computers are
realized will jeopardize the security of public key cryptosystems which are
widely deployed within communication protocols, digital signing mechanisms,
authentication frameworks, and more. To avoid this, NIST has actively led a PQC
standardization effort since 2016, leveraging a large and international
research community.
  On January 31-February 1, 2019, the Computing Community Consortium (CCC) held
a workshop in Washington, D.C. to discuss research challenges associated with
PQC migration. Entitled, "Identifying Research Challenges in Post Quantum
Cryptography Migration and Cryptographic Agility", participants came from three
distinct yet related communities: cryptographers contributing to the NIST PQC
standards effort, applied cryptographers with expertise in creating
cryptographic solutions and implementing cryptography in real-world settings,
and industry practitioners with expertise in deploying cryptographic standards
within products and compute infrastructures. Discussion centered around two key
themes: identifying constituent challenges in PQC migration and imagining a new
science of "cryptographic agility".
