Abstract

In the article the method of the distributed data storing is considered. The method is based on the model when any ftle is represented as a (N, k) threshold scheme. The algorithms of splitting and assembling offiles are based on finite field fields math (Galois field GF). The file is represented as a sequence of K-dimension vectors above GF(2") field, and each part of the file in the threshold scheme is a sequence of projections of these vectors on some selected for the given part K-dimension vector above GF. In the article the implementation of the method for n=16 is adduced and the method application is researched to provide availability ofthe Internet-service systems.
