Abstract
An information processing method, includes calculating, using a first station, an estimated ratio of a quantity of pulses affected by a photon-number splitting (PNS) attack including a multi-photon in the pulses to a total quantity of the pulses, performing, using the first station, error correction processing on key information based on the estimated ratio to obtain a shared key of the first station and a second station when the estimated ratio is less than a preset threshold. Hence, a degree to which the photon is affected by the PNS attack can be estimated in order to perform error correction on the key information, thereby improving security of a key distribution.
