Post-quantum cryptography (PQC) is a new generation of encryption designed to survive attack by quantum computers — and UAE businesses need to start migrating now, because data stolen today can be decrypted later once a capable quantum machine exists. The UAE has already approved a National Encryption Policy requiring a transition to quantum-safe encryption, making this a compliance question as well as a technical one.
For most organisations, quantum computing still sounds like a problem for the 2030s. It is not. The threat model that matters today is called “harvest now, decrypt later”: adversaries intercept and archive encrypted traffic now — contracts, health records, financial data, intellectual property, government correspondence — and simply wait until a cryptographically relevant quantum computer can open it. If the data you transmit today still needs to be confidential in 2033, it is already exposed.
The maths has moved faster than most boards realise. Research published between 2025 and 2026 cut the estimated quantum resources needed to break RSA-2048 from roughly 20 million qubits to under one million, and by some newer architectures as low as 100,000. Nothing has been broken yet — but the runway is shortening while enterprise migrations still take years.
Why this is now a UAE compliance issue
The UAE is not waiting. The Cabinet has approved a National Encryption Policy that requires government entities to transition to post-quantum cryptography with defined plans to move off traditional encryption, overseen by the UAE Cyber Security Council.
In May 2026, the Cyber Security Council signed an agreement with the Advanced Technology Research Council (ATRC) to accelerate the national quantum-safe transition, built on cryptographic libraries from the Technology Innovation Institute (TII), QuantumGate’s Crypto Discovery Tool, and entanglement-based quantum key distribution commercialised by VentureOne. A National Cryptography Discovery Platform, aligned to requirements set by the UAE National Cryptography Centre, now lets critical public and private sector entities inventory their cryptography and plan a structured migration. This is one of the world’s first coordinated national post-quantum migration programmes.
Across the wider GCC the direction is consistent: Saudi Arabia enforces cryptographic hygiene through national controls, while Qatar, Kuwait, Bahrain and Oman are folding quantum risk into their broader cybersecurity frameworks. Internationally, NIST has designated RSA-2048 and ECC P-256 for deprecation by 2030 and disallowance by 2035. If you sell into government, banking, healthcare or critical infrastructure, PQC readiness will start appearing in tenders long before those dates.
What actually breaks — and what does not
At risk: public-key cryptography
Quantum attacks target the asymmetric algorithms that underpin key exchange and digital signatures — RSA, Diffie-Hellman and elliptic-curve cryptography. That means TLS on your websites and APIs, VPN and SD-WAN tunnels, code signing, VPN certificates, smart cards, secure email and most PKI.
Largely safe: symmetric cryptography
Symmetric algorithms such as AES-256 and modern hashes like SHA-384 remain sound; the practical guidance is to move to longer keys rather than replace the algorithm. So the migration is narrower than it first appears — but it touches nearly every system that talks to another system.
A practical five-step migration plan
1. Build a cryptographic inventory
You cannot migrate what you cannot see. Discover every place your organisation uses public-key cryptography: certificates, VPN concentrators, load balancers, application libraries, HSMs, IoT and OT devices, and third-party SaaS. This inventory — a cryptographic bill of materials — is the single most valuable artefact you will produce, and it is where the UAE’s discovery tooling is aimed.
2. Classify data by shelf life
Rank data by how long it must stay confidential. Anything with a ten-year-plus secrecy requirement — patient records, M&A material, long-term contracts, national-security-adjacent data — is the harvest-now target and should move first.
3. Push the problem to your vendors
Most of your cryptography is not yours; it is in products you buy. Ask every vendor for a written PQC roadmap, and write quantum-safe requirements into new contracts and renewals now. Vendor lead time, not your own engineering, is usually the long pole.
4. Pilot hybrid key exchange
Hybrid modes combine a classical algorithm with a post-quantum one (for example ML-KEM), so you gain quantum resistance without betting everything on a new algorithm. Major browsers and cloud providers already support hybrid TLS — start with internet-facing TLS and site-to-site tunnels, where the benefit is highest and the change is contained.
5. Design for crypto-agility
The real goal is not to deploy one new algorithm; it is to be able to swap algorithms again without a multi-year project. Centralise certificate management, remove hard-coded crypto from applications, and shorten certificate lifetimes so change becomes routine.
Be realistic about timing: a serious enterprise migration runs roughly 42–54 months from inventory to compliance. Organisations starting in 2026 against a 2030 deprecation date have no slack for delay.

Frequently asked questions
Is post-quantum cryptography mandatory in the UAE?
The UAE Cabinet has approved a National Encryption Policy requiring government entities to transition to post-quantum cryptography with defined migration plans, overseen by the UAE Cyber Security Council and supported by a National Cryptography Discovery Platform. Private-sector organisations are not universally mandated yet, but critical-infrastructure operators and government suppliers should expect quantum-safe requirements to appear in regulation and tenders well before NIST’s 2030 deprecation of RSA-2048 and ECC P-256.
What is “harvest now, decrypt later”?
It is an attack in which adversaries capture and store encrypted data today, with no ability to read it, so they can decrypt it years later once a cryptographically relevant quantum computer exists. It matters because it removes the option of waiting: any data you transmit now that must remain confidential into the 2030s is already at risk, regardless of when quantum computers actually arrive.
Do we need to replace AES and all our encryption?
No. Quantum attacks primarily threaten public-key algorithms such as RSA, Diffie-Hellman and elliptic-curve cryptography — the ones behind TLS, VPNs, PKI and code signing. Symmetric encryption such as AES-256 and hashes such as SHA-384 remain sound, and the guidance is simply to use longer keys. The work is concentrated in key exchange, certificates and digital signatures.
