Abstract

Secure data distribution is a key link to build reliable distributed storage. Aiming at the problems existing in exis-ting data security distribution schemes, such as "insufficient key protection capability and severe resource consumption caused by large-scale decoding and re-encryption of data after key leakage", this paper proposed a data security distribution scheme: LS&SSS-RS. In this scheme, the key and ciphertext were stored separately, the Latin square of the key was secretly shared by the Latin square and the Shamir scheme, and the ciphertext was distributed stored by RS coding. The experimental results show that the scheme avoids the direct exposure of key sharding, improves the fault tolerance of the sharding, and saves a lot of data update time after the key sharding is leaked. In addition, the loss of some data does not affect the integrity of the original data, avoids the single point of failure, and improves the fault tolerance of distributed storage system. The analysis shows that the scheme can overcome the potential security risks, protect the key security effectively, and save a lot of time and computing resources.
