The RRDPS key length, Takesue, Sasaki, Tamaki & Koashi (2015), Methods
6/6 passed in 1ms
| Test | What it does | Result |
|---|---|---|
test_block_monotone | The length and the length per emitted packet both rise with the block, the two hash terms and the three thresholds all being amortised. | ✅ pass |
test_double_price | Observed double clicks raise the multiphoton threshold and shorten the length. | ✅ pass |
test_leak_independent | Changing the bit error rate moves no threshold, so the whole change in length is the leakage fn_sift(h2(0.05) - h2(0.01)). | ✅ pass |
test_length_units | The length is whole bits, never negative, and zero on a block too short to certify. | ✅ pass |
test_rate_converge | CROSS-ENGINE. The length per sifted bit closes from below on 1 - f h2(e_bit) - h2(e_ph) at exponent -0.5006 over three decades from 1e9. | ✅ pass |
test_sift_guard | More sifted bits than emitted packets is refused. | ✅ pass |
