January 14, 1998 - A New and Efficient All-or-Nothing Disclosure of Secrets Protocol
by Julien P. Stern
| Abstract: | The All-Or-Nothing Disclosure of Secrets Protocol (ANDOS) was introduced in 1986 by Brassard, Crépeau and Robert. It involves two parties, a vendor and a buyer, and allows the vendor, who holds several secrets, to disclose one of them to the buyer, with the guaranty that no information about the other secrets will be gained. Furthermore, the buyer can freely choose his secret and has the guaranty that the vendor will not be able to find out which secret he picked. In this talk, we present a new protocol which achieves the same functionality, but which is much more efficient and can easily be implemented. Our protocol is especially efficient when a large number of secrets is involved and it can be used in various applications. |
