Hirota and P. Tombesi, eds., (Kluwer, New York, 2001) Abstract A new cryptographic tool, anonymous quantum key technique, is introduced that leads to unconditionally secure key distribution and encryption schemes that can be readily implemented experimentally in a realistic environment. If quantum memory is available, the technique would have many features of public-key cryptography; an identification protocol that does not require a shared secret key is provided as an illustration. The possibility is also indicated for obtaining unconditionally secure quantum bit commitment protocols with this technique.         Home | About the Program | Our Research | Publications | People Related MURIs | Contact © Massachusetts Institute of Technology
