Abstract
A fiber optic light intensity encryption method is provided. The method includes determining light intensities associated with multi-frequency light pulses emitted by a laser transmitter apparatus in response to an encryptions process. An encryption type for application of an encryption algorithm to each light intensity is determined and a first light intensity associated with a first light pulse is selected. Data indicating results of the random selection is transmitted to the laser transmitter apparatus and an initial security key is transmitted over a signaling channel of the laser transmitter apparatus. The signaling channel is secured based on the initial security key resulting in a secure signaling channel. In response, a secure bundle comprising said the secure signaling channel and an additional group of channels is generated and the data is transmitted via the secure bundle.
