Abstract
We consider a family of quantum communication protocols involving N partner s. We demonstrate the existence of a link between the security of these pro tocols against individual attacks by the eavesdropper, and the violation of some Bell's inequalities, generalizing the link that was noticed some year s ago for two-partners quantum cryptography. The arguments are independent of the local hidden variable debate.
