As progress is being made towards large scale quantum computers, governments, critical infrastructure, and enterprises are waking up to the foreseen risks on public key cryptographic systems and the Store Now Decrypt Later threats (otherwise known as passive quantum attacks). Post Quantum Migration Laws and regulations are being put in place globally (incl. UAE’s new Cryptography Executive Regulation, the National Security Advisor Decision No. (71) of 2024 Concerning Federal Decree No. (8) of 2023).
The time to Act is Now!
As we prepare to deploy quantum safe cryptographic solutions, adoption challenges are likely to surface. Proper planning and balanced PQC migration roadmaps, supported by the right toolset and solutions are criticial.
- Cryptographic Discovery: discovery tools are required to establish inventories and to identify where and for what purpose public-key cryptography is being used
- Multiple PQC algorithms will be needed to address different applications (i.e., large vs. small keys constraints, digital signatures size, latency thresholds, amongst other factors)
- Changes to existing protocols might be required for the integration of key encapsulation mechanisms and quantum safe digital signatures
- Cryptographic agility is essential: cryptographic components and the standards around them lack agility, meaning that newer primitives, adaptations and any structural changes cannot be done without a significant impact in the system’s infrastructure; it is therefore critical to Introduce security abstraction layers as a mean of creating pluggable cryptographic libraries within proposed Quantum solutions
- Backwards compatibility and interoperability will be key as classical cryptography is being phased out; a hybrid classical – Quantum safe approach will be initially required
- More concentrated efforts are required to study complementarity between Post Quantum Cryptography and Quantum Communication / Quantum Key Distribution (QKD) Systems and propose hybrid deployment and key management approaches
