Post-quantum cryptography fully implemented today — not a roadmap promise
Quantum computers will break conventional encryption. That is why post-quantum algorithms are already fully implemented in Silentel — not merely promised on a roadmap. Secure today for your future!
Conventional ECC and PQC in parallel — backwards-compatible and future-proof at the same time.
Communications intercepted today cannot be decrypted even with quantum computers.
Optimised implementation: no difference in latency or battery life.
The first government solution for iOS and Android with PQC and NATO approval.
Already compliant with forthcoming EU requirements (NIS2, eIDAS 2.0) and NATO standards.
The attack does not wait until quantum computers become available. It is happening now.
The key question is how long your content must remain confidential, rather than when quantum computers will be available. Harvest Now, Decrypt Later works in three steps:
Encrypted communications are already being systematically intercepted and archived — to decrypt later, rather than read today.
Once powerful quantum computers become available, they will break today's common asymmetric methods — and thus anything transmitted with exclusively conventional protection.
If your content must remain confidential for 10 or more years, conventional encryption is already insufficient today. Anything sent with Silentel has an additional PQC encryption layer — and remains unreadable even to future quantum computers.
PQC is not an optional extra in Silentel. It adds another layer over a foundation already overengineered even without the quantum threat:
The parameters used exceed the approved requirements for Top Secret (CNSA). In addition, post-quantum cryptography under FIPS 203, 204 and 205 is fully implemented — as an additional encryption layer over all communications, not a beta feature. Full details: Features & Functions →
ICSL was one of the first COMSEC providers in the DACH region to deploy post-quantum cryptography in production — as standard, not in beta.
Encryption methods that also withstand attacks by quantum computers. The methods used in Silentel are standardised under FIPS 203, 204 and 205 — and are already in production use today, not merely announced.
No — it complements it. Conventional methods (ECC) and PQC run in a hybrid parallel configuration: the PQC layer adds encryption over all communications. The solution remains backwards-compatible and future-proof at the same time.
No. PQC is fully implemented in software on iOS, Android and Windows, with no noticeable difference in latency or battery life.
No reliable date can be given — and that is precisely the point: what matters is your data's required protection period. Anything intercepted today must still be unreadable when that time comes. That is why now is the right time for PQC.
The solution is already compliant with forthcoming EU requirements (NIS2, eIDAS 2.0) and NATO standards — as the first government solution for iOS and Android with full PQC implementation and NATO approval. More on proven reliability →
