RAMP splits quantum key generation from user-side key masking
Original title: RAMP: Toward Ubiquitous Quantum-Safe Key Distribution as a Service
Commodity endpoints distilled service-provisioned material at 2.1 Kb/s on an M4 Pro CPU.
A paper presents RAMP, a framework that lets providers supply raw quantum-key-distribution material while users mask and locally process it into final keys without operating QKD devices. Reconciliation-preserving masking is compatible with both DV- and CV-QKD. The authors formalize dual-domain guarantees: colluding providers exposing raw-key views do not reveal the final key if the masking domain stays secure, and exposing the masking state does not break secrecy if the QKD source and acquisition paths stay protected. They implement RAMP with experimentally acquired QKD data and standardized quantum-safe cryptography.
Unconfirmed: The claim of a first experimental realization is the authors' own, qualified as to their knowledge.
- Average user-side key-distillation throughput was 2.1 Kb/s on an M4 Pro CPU.
- Masking is described as compatible with DV-QKD and CV-QKD.
- Providers operate QKD infrastructure and supply raw-key materials.
- The authors call this the first such experimental realization, to their knowledge.

From the original article
1 min read at arxiv.orgQuantum key distribution (QKD) offers a security foundation independent of computational hardness assumptions. However, its reliance on specialized hardware limits access by ordinary users. Turning QKD into a service poses a fundamental trust challenge, as the providers that supply QKD-derived material themselves could retain knowledge of the keying inputs of users.
