In secret sharing protocols, a secret is to be distributed among severalpartners so that leaving out any number of them, the rest do not have thecomplete information. Strong multiqubit correlations in the state by whichsecret sharing is carried out, had been proposed as a criterion for security ofsuch protocols against individual attacks by an eavesdropper. However we showthat states with weak multiqubit correlations can also be used for securesecret sharing. That our state has weak multiqubit correlations, is shown fromthe perspective of violation of local realism, and also by showing that itshigher order correlations are described by lower ones. We then present aunified criterion for security of secret sharing in terms of violation of localrealism, which works when the secret sharing state is theGreenberger-Horne-Zeilinger state (with strong multiqubit correlations), aswell as states of a different class (with weak multiqubit correlations).Comment: 7 pages, no figures, RevTeX
