Secure communication with secret sharing in static computer networks with partition in mistrust parties

This paper presents a solution to ensure arbitrarily secure communication in a large computer network by using secret sharing and multiple parties mistrusting each other instead of relying on some “trusted party” or a “web of trust”. In contrast to other solutions that use a PKI and require asymmetric encryption, this concept can guarantee to provide secure communication even after any possible advance in cryptanalysis and even if unlimited calculation power was available to attack it. But this solution requires the computer network to have special properties. It is mainly intended to be used in the S-Network, a repository for reliable publications.
