Cheating prevention in secret sharing over GF(pt)
Pieprzyk, Josef & Zhang, Xian-Mo (2001) Cheating prevention in secret sharing over GF(pt). In Pandu Rangan, C. & Ding, C. (Eds.) Progress in Cryptology - INDOCRYPT 2001, Springer, Chennai, India, pp. 79-90.
The work investigates cheating prevention in secret sharing. It is argued that cheating is immune against cheating if the cheaters gain no advantage over honest participants by submitting invalid shares to the combiner. This work addresses the case when shares and the secret are taken from GF(pt). Two models are considered. The first one examines the case when cheaters consistently submit always invalid shares. The second modeldeal s with cheaters who submit a mixture of valid and invalid shares. For these two models, cheating immunity is defined, properties of cheating immune secret sharing are investigated and their constructions are given.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
