Problems solved by technology

In the case of constantly changing encryption technology, many mature encryption software have appeared, such as encrypted EncFS and eCryptfs based on the stack file system. However, after encrypting data through these encryption software, attackers can use file comparison technology to The encrypted data is decrypted, which makes the data easy to be cracked. Therefore, the existing encryption software has low security

Abstract

The invention discloses a data encryption method and computing equipment. The method comprises the following steps: acquiring to-be-encrypted data; storing the to-be-encrypted data in a tree structure, wherein the maximum storage capacity of each node in the tree structure is the same, and all leaf nodes except the rightmost leaf node in the tree structure store the data with the maximum capacity; encrypting each node corresponding to the to-be-encrypted data in the tree structure through an encryption algorithm; and storing the encryption key of each node in a father node of the node. According to the method, the to-be-encrypted data is divided into the plurality of data blocks, the data blocks are stored in the tree structure, each node in the tree structure stores the data block or the data block pointer, and each node in the tree structure is encrypted, so that metadata and real data are protected, and the security of data encryption is improved. Moreover, the encryption key of each node is stored in the father node of the node, so that the decryption difficulty is high, and the security of data encryption is further improved.

Description

technical field [0001] The present invention relates to the technical field of encryption, in particular to a data encryption method, computing equipment and a storage medium. Background technique [0002] With the continuous development of information technology, the data security of individuals and enterprises has become more and more important. How to ensure data security has become a current hot spot. In the case of constantly changing encryption technology, many mature encryption software have appeared, such as encrypted EncFS and eCryptfs based on the stack file system. However, after encrypting data through these encryption software, attackers can use file comparison technology to Decrypting the encrypted data makes the data easy to be cracked. Therefore, the existing encryption software has low security. [0003] Therefore, the present invention provides a data encryption method that can improve data security. Contents of the invention [0004] For this reason, t...
