Since Yuen 2000 protocol (Y-00) was introduced as a way of realizing Gauss-Yuen random cipher with the possibility of information-theoretic security, there have been many studies for the purpose of establishing evaluation theory of Y-00's security.
The concept of this new random cipher is different from the framework of traditional cryptographic theory. Therefore, this concept has been misunderstood and underappreciated. Ahn and Birnbaum started information-theoretic discussion in which they criticized Y-00. Against their criticism, however, Nair and Yuen proved that Ahn and Birnbaum confused Shannon's random cipher with our random cipher and that their conclusion was meaningless. This paper will introduce their criticism and discuss the possibility that the model, which was introduced my previous paper published in Physical Review A, 2007, may become the cipher with information-theoretic security of practical quantitative capability. |
