Ensuring the security of RFID’s large-capacity database system by depending only on existing encryption schemes is unrealistic. Therefore, data sharing for security management to supplement it is drawing attention as an extremely secure scheme. However, applying the existing secret sharing scheme to this method makes the size of the share equal to that of the original data. Thus, it is not suitable for application to large-scale database. This paper proposes secret sharing algorithms that enable efficient data sharing security management based on the characteristics of the All-Or-Nothing Transform encryption mode. The proposed algorithms enable fast sharing and reconstruction in terms of processing speed and allow the sum of shares to be equal to that of the plaintext, thereby making them suitable for large-capacity database storage.
