METHOD OF SECURING DATA USING THRESHOLD CRYPTOGRAPHY

摘要

It is an object of the present invention to provide a method of securing data using threshold cryptography in which data are encrypted using cryptographic algorithms and cryptographic key is split onto shares. Method of securing data using threshold cryptography is characterized with that unique identifier is assigned to encrypted data. Subsequently, at least one share of cryptographic key is merged with encrypted data. Next, encrypted data merged with some of key's shares is split onto fragments and unique identifier previously assigned to encrypted data is added to each fragment. The same unique identifier is added to each key's share that was not merged with encrypted data. Obtained fragments of data are deployed on physically separated devices consisting of at least one processor and one non-volatile memory and for each fragment information about device on which it is deployed is saved. Key's shares that were not merged with encrypted data are placed on physically separated devices consisting of at least one processor and non-volatile memory and for each share of key information about device on which it is stored is saved.
