WebThe periods are randomized by scanning the pseudo-random bit sequence for occurrences of bit patterns. No explicit in- formation about the change of key is necessay during transmission. The statistical model shows a deviation from the geometrical distribution due to overlapping between bit patterns. WebIn general, choosing a cryptoperiod is really about risk management. You look at all of the risks related to key exposure (cryptanalysis, key compromise, etc.). If the risk is …
