RELIABLE CLOUD STORAGE SYSTEM WITH ADJUSTABLE DATA REDUNDANCY Russian patent published in 2022 - IPC G06F7/72 G06F7/38 

FIELD: computing systems.

SUBSTANCE: invention relates to computing systems. A reliable cloud storage system with adjustable data redundancy, consisting of blocks for finding remainders modulo p_i(x), an error correction block, and a block for converting to a positional number system, contains k+r blocks for finding remainders modulo p_i(x), where p_i(x) are coprime trinomials of the form p_i(x)=x¹⁵+x^a+1 over the field F₂, where a=[1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 13, 14] and 2≤k≤11, (k+r)<12, whose inputs are connected to the input of the original number, and the outputs are connected to the input of the corresponding XOR block of the transmitting half and the upper bits of the register for storing transmitted parts modulo pi(x), the least significant bit of which is connected to output of the corresponding XOR block of the transmitting half, the outputs of the storage registers of the transmitted parts modulo pi(x) are transferred to the cloud infrastructure for storage and/or processing.

EFFECT: increasing the reliability of cloud storage (polynomial RNS) and the ability to control redundancy.
