Industry experts warn that a cryptographically relevant quantum computer, which could implement Shor’s algorithm with large enough data sets, will be available by the end of the decade. Since history has shown that cryptographic migrations are much more complex and lengthier than expected, the importance of mitigating the HNDL threat timely should not be underestimated. We will review how organizations can now leverage multiple cryptographic technologies (PQC&QKD) to both lower the migration risks and costs, as well as to achieve long-term resilience against the rapidly emerging quantum threat.
