Random number generation from a self-chaotic broad-area VCSEL

Jules Mercadier, Marc Sciamanna, Stefan Bittner, Yohann G. Sanvert

Broad-area VCSELs produce intrinsic chaos that supports random number generation at 150 Gb/s without external perturbations.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The nonlinear dynamics of transverse and polarization modes of a broad-area VCSEL exhibit, without any external perturbation, chaos with high correlation dimension, large bandwidth, and good spectral flatness over a wide range of currents. We leverage this for high bit-rate entropy generation and random number generation (RNG), passing the NIST tests with rates up to 150 Gb/s.

C2weakest assumption

That the observed chaos produces bits that are truly unpredictable and free of hidden correlations or biases not detected by the NIST test suite, and that the correlation dimension reliably indicates sufficient entropy for cryptographic use.

C3one line summary

Self-induced chaos in a broad-area VCSEL enables high-speed random number generation up to 150 Gb/s passing NIST tests without external perturbations.
