How to Share a Secret with Cheaters
Advances in Cryptology — CRYPTO' 86
This paper demonstrates that Sharnir's scheme ("How to share a secret", Communications of rhe ACM, vol. 22, no. 11, November 1979,612-613) is not secure against cheating. A small modification to his scheme retains the security and efficiency of the original, i s secure against cheating, and preserves the property that its security does not depend on any unproven assumptions such as the intractability of computing number-theoretic functions.doi:10.1007/3-540-47721-7_20 dblp:conf/crypto/TompaW86 fatcat:uxb3liqqsnaqdgszqvoeggzowu
