| Abstract(in English) | As a method to distribute and preserve secret information, a secret sharing scheme provides high confidentiality and redundancy. On the other hand, in order to recover some codeword symbols, the locally repairable code was proposed. The locally repairable codes can recover an unavailable codeword symbol from a small number of other codeword symbols. In this paper, we propose a secret sharing scheme using locally repairable codes obtained by Tamo and Barg, and show information theoretic security of the proposed scheme and analyze its access structure. We clarify that the proposed method achieves the ideal encoding efficiency as a perfect secret sharing scheme and enables the local repair of distributed shares. |
