چکیده
The quantum-mechanical description of coherent light, as produced by lasers, gives rise to an intrinsic noise, known as quantum noise, optical noise or shot noise. Several protocols have been proposed to exploit this physical phenomenon to obtain secure data encryption and key distribution. Here we focus on the cryptographic aspects of Barbosa’s protocol[1] and propose an improvement, which is inspired on the concept of a pool of randomness as used by random bit generators in operating systems.
