Questions leaders ask
What did TETRA:BURST and 2TETRA:2BURST find?
TETRA:BURST, published by Midnight Blue on 24 July 2023, disclosed five vulnerabilities in the TETRA air interface. The critical ones were CVE-2022-24402, a TEA1 algorithm whose 80-bit key reduces to a size that can be brute-forced in minutes on commodity hardware, and CVE-2022-24401, a keystream generator that relies on unauthenticated network time and allows decryption oracle attacks. 2TETRA:2BURST, presented at Black Hat USA on 7 August 2025, moved to end-to-end encryption and key management: CVE-2025-52941, an end-to-end algorithm whose effective key drops from 128 to 56 bits, CVE-2025-52943, a network key identical across every air interface algorithm a network supports, and CVE-2025-52944, message injection even with authentication enabled. None of this needed a quantum computer. It shows how long a weakness can sit inside a public safety network before anyone outside the vendors can look.
Has ETSI fixed TETRA, and are TEA5, TEA6 and TEA7 quantum-safe?
ETSI's TETRA committee agreed in November 2023 to publish every air interface algorithm, and did so in February 2025: TS 104 053-1 for TEA Set A, the original TEA1 to TEA4, and TS 104 053-2 for TEA Set B, the TEA5, TEA6 and TEA7 ciphers with 192-bit keys. Symmetric ciphers with 192-bit keys are not the part of the stack a quantum computer breaks first. The exposure is in everything that authenticates and distributes keys, in the IP links between sites and systems, and in a network that still has TEA1 enabled alongside a stronger cipher. Ask your vendor and your national programme which set your network runs, with the published specifications in hand.
Does NIS2 apply to police, fire and ambulance services?
It depends on how your Member State drew the lines. NIS2 covers public administration entities of central government, regional entities that a Member State's risk assessment identifies as significant, and local bodies only where a Member State opts them in. Entities whose activities are in national security, public security, defence or law enforcement can be excluded. In practice an ambulance service may be a health sector entity under Annex I while the police force next door sits outside NIS2 and inside national law enforcement rules instead. Whichever applies, Article 21 asks for policies on cryptography and encryption, and Article 20 puts the management body in charge of approving and overseeing them. The Directive had to be transposed by 17 October 2024.
What does the Critical Entities Resilience Directive change for emergency services?
The CER Directive (EU) 2022/2557 names public administration among its eleven sectors, alongside health, digital infrastructure, transport, energy and space. It applies from 18 October 2024, asked Member States to adopt a national resilience strategy by 17 January 2026 and to identify their critical entities by 17 July 2026. An identified critical entity must assess its risks and take resilience measures across physical and cyber dependencies. If your service or the network it depends on has been named, the dependency on cryptography that a quantum computer will break belongs in that assessment.
Where does the UK Emergency Services Network stand?
The Home Office page updated in February 2025 counts more than 300,000 frontline users, 45,000 vehicles, over 90 aircraft and around 200 control rooms that will depend on ESN. EE was awarded the mobile infrastructure contract in December 2024 and IBM leads design, build and integration from January 2025. The summary business case of 27 July 2026 puts the whole-life budget at GBP 19.1 billion to 2043/44 with GBP 6.1 billion spent, extends the EE/BT contract to 2031 and targets Airwave shutdown when it is safe to do so, without naming a year. Plan for TETRA and mission-critical LTE running side by side into the 2030s, and ask the programme how post-quantum key management fits the ESN releases.
Is mission-critical push-to-talk on LTE and 5G quantum-safe?
Not yet. 3GPP standardised MCPTT in Release 13 in 2016 and MCVideo and MCData in Release 14, with security in TS 33.180. Those services establish identity and keys with public-key cryptography, which is exactly what a cryptographically relevant quantum computer breaks. The 3GPP security groups are working on post-quantum options for the 5G system, and CISA's January 2026 product categories list still places networking and radio hardware among the categories in transition. The migration will come from the national network operator and the application vendors; your job is to know your dependencies and ask for dates.
Why does harvest now, decrypt later matter for a blue-light service?
Because the data lives longer than the algorithm. Police records on serious offences and public protection matters are retained until the subject is deemed to be 100. Children's health records, including the ambulance patient record, are kept to the 25th birthday. Investigation and intelligence material identifies victims, witnesses, informants and officers for a lifetime. Traffic recorded in 2026 and read in the 2030s lands well inside those windows. The National ANPR Service, by contrast, deletes reads after 12 months, which is a reminder that the live link, not just the archive, is what an adversary records.
Where should an emergency service start?
With four things. A cryptographic inventory of control room and dispatch systems, records systems, the interfaces to the radio and MCX networks and the device fleets. A map of which records must stay confidential beyond 2030 against the algorithms protecting them. Confirmation of which TETRA algorithm set the network runs, whether TEA1 is disabled and when the keys were last rotated. And roadmaps requested from the national programme, the operator and every radio, control room, body-worn and drone vendor. Those four give the chief officer team or authority the evidence to set priorities.
Is quantum key distribution an option for control room backbones?
Possibly for a fixed fibre link between two sites, and several of our lectures cover national QKD networks. It does not authenticate, does not sign firmware or evidence, and does not run on a handset, a body-worn camera or a drone. The NCSC and the EU roadmap both point to post-quantum algorithms as the baseline. Treat QKD as a complement for one high-assurance link, not a substitute for the migration, and run the QKD Network Readiness Qualifier before anyone writes it into a tender.
What does QSECDEF offer police, fire and ambulance services for free?
Everything on this page. The two-minute readiness check scores your service and routes you to the right next step. The free tools, including the HNDL Risk Calculator and the Third-Party Cryptographic Exposure Model, run in your browser with no registration. The weekly peer call runs every Tuesday at 15:00 CET and is open to anyone. Sample lectures from the 170-plus expert library are linked above, and the page is reviewed as the mandates change; the date beside the key facts is the last check.
Which QSECDEF course should an emergency services team take first?
It depends on the role. Chief officers, authority members and directors start with the Certified Quantum Business Professional bootcamp, about 22 hours self-paced across ten modules. Security, IT and control room systems teams take Introduction to Quantum Cyber Security, four to five hours online with a QSECDEF certificate. Communications engineers and network security leads take PQC Migration for Emergency Communications: TETRA, LTE, and 5G, the sector course for TETRA, MCPTT and 5G MCX. Whoever will run the migration takes CPQCPM, the Certified Post Quantum Cryptography Programme Manager course: ten hours live online over five weeks, with the next public cohort in January 2027.
Can QSECDEF run private training or a workshop for our service, programme or supplier?
Yes. QSECDEF runs private CPQCPM cohorts for a single organisation, live online or in person, and private deliveries of the sector courses listed under Equip your people for your communications and control room teams. Board and leadership workshops are built on your own exposure and obligations and end with an agreed position on quantum risk. Use the contact button in the For your organisation section and tell us your timeline.
How do we find vetted suppliers or consultants for an emergency services PQC migration?
Through the QSECDEF Expert Members directory. Every listed member has been vetted, has signed the Members' Charter and has presented to the community. You can filter by consulting and services, technology vendor or enablement and investment, and send a request for further information from the member's own page. QSECDEF is vendor-neutral and sells training, not migration products, so the shortlist stays yours.
Is QSECDEF membership relevant to a police, fire or ambulance service?
Two routes. QSECDEF membership gives your team the self-paced courses, the full lecture archive, the weekly call and 25 per cent off CPQCPM and partner training. Expert Membership is for the builders, consultancies and technology vendors serving emergency services who want to be found by the people reading this page; it includes a showcase listing with an enquiry form, the Industry Conversations and speaking slots at the annual QSECDEF symposium.
Is QSECDEF selling a migration product?
No. QSECDEF is a vendor-neutral membership network. We train people and connect them with peers and peer-reviewed experts; we do not sell migration software or services.
How much time does the training take?
CPQCPM is ten hours of live instruction over five weeks, two hours a week. The Quantum Cyber Security course is 4 to 5 hours, self-paced. The business bootcamp is self-paced at your own speed. The emergency services courses are one-day workshops of six hours, listed with their formats on the training pages.
