Safe data deletion method based on solid-state disk array

The invention discloses a safe data deletion method based on a solid-state disk array. Based on the parallel operation of multiple solid state disks in the solid state disk array, the secret sharing algorithm is used to convert the data and distribute the encoded data to each solid state disk. On one hand, the encoding guarantees the data redundancy and the converted data is ciphertext, which improves the reliability and security of the data. On the other hand, by using the characteristic of fault-tolerant coding, the deletion of data does not need to overwrite the whole data, but deletes partof the data, destroys the integrity of the data and makes the data can not be recovered. Even if the attacker gets part of the encoded data, it can not get the plaintext to achieve the purpose of safely detecting the data. The invention solves the safety problems of data storage such as unreliable storage of the solid-state disk array and unsafe deletion of files. 本发明公开了种基于固态盘阵列的数据安全删除方法，利用固态盘阵列中多个固态盘可并行操作的特点，采用秘密共享算法对数据
