and Elliptic Curve Cryptography (ECC), designed on the theory of large number factoring and finding the discrete logarithm problem, as well as simplification, could very well be broken by quantum computers of sufficient power.
With quantum computing’s physiologically extending capabilities, it is imperative for organizations to navigate it as a digital transformation to post-quantum cryptography (PQC). PQC embraces a collection of cryptographic algorithms purposefully crafted to stay secure against both classical and quantum computers.
Missing the critical transition to PQC could provoke some troubling repercussions, like data being compromised, intellectual property being detected, and confidential transmissions being accessed.
In this article, we examine PQC as essential, discuss its implementation at the cost of existing TLS algorithms, and provide a thorough migration guide to enable organizations to plan and conduct a PQC migration strategy successfully.
Understanding Post-Quantum Cryptography (PQC)
Post-quantum cryptography (PQC) is the name of a cryptographic algorithm that is considered to work against an attack from classical devices and quantum computers. The specific algorithms arise from the computation problems that may be considered to be hard even by the use of the QC computation output.
Complementarily, PQC algorithms offer the same level of security and performance as traditional types of encryption with an added layer of safeguard against the possibility of an attack that quantum computations present.
Why think ahead and program PQC now?
Unlike the massive classical computers, the invention of large-scale quantum machines that are known to crack the present spying techniques has no well-defined time frame as to when it is expected to be developed, and therefore the threat is imminent.
Here are a few key reasons why organizations should start planning for PQC migration now:
Long Lifespan of Sensitive Data:
Another feature that has proven to be more secure now is encryption, more so because much of the data can be hacked, which was founded many years or even decades ago when quantum computing might be a reality.
Lengthy Migration Process:
The transition to PQC is a long and intricate process because of the several factors to cover which include identification of the risks, rectifying the systems and applications, integrating new cryptographic protocols, and updating the compatibility in the different platforms.
Future-proofing:
Starting the planning and implementation at this time, the organizations will pre-prepare their systems and structures for change to quantum-ready cryptology for ease of transitioning at some point.
Staying Ahead of Threats:
This way, by adopting PQC through projection and preparation, organizations would stay ahead of the entire quantum computing threats and ensure that no foothold is provided that is weaker compared to others.
NIST-Approved PQC Algorithms
NIST has spearheaded this initiative since long ago by organizing competitions open to the public and profoundly evaluating cryptographic algorithms (PQC).
In July 2022, NIST announced the first four PQC algorithms as acceptable for general use:
CRYSTALS-Kyber: The most critical aspect of developing the system is a securely encrypted key encapsulated into an abstract algebra which is a lattice.
CRYSTALS-Dilithium: Therefore, an algorithm for the digital signature is presented based on such a multifactorial grid as has been mentioned above.
FALCON: An algorithm of digital signature employing the problem of finding short vectors of ideal lattices.
SPHINCS+: To provide a method of digital signatures with a hash function.- As the first step, these algorithms are expected to set up a cryptographic standard to verify the integrity, authenticity, and confidentiality of the information exchanged during the quantum era.
