摘      要:We propose a new approach to the generation of an alphabet for secret key exchange relying on small variations in the cavity length of an ultralong fiber *** new concept is supported by experimental results showing how the radiofrequency spectrum of the laser can be exploited as a carrier to exchange *** test bench for our proof of principle is a 50-km-long fiber laser linking two users,Alice and Bob,where each user can randomly add an extra 1-km-long segment of *** choice of laser length is driven by two independent random binary values,which makes such length become itself a random *** security of key exchange is ensured whenever the two independent random choices lead to the same laser length and,hence,to the same free spectral range.
