Abstract

The invention discloses an information processing method and device and a storage medium. The method comprises the following steps: firstly, acquiring a data segment encrypted by using a first key, the data segment being a data segment of a data file; obtaining a first secret key corresponding to the data segment; then, carrying out exclusive-OR operation on each byte in the data segment by usinga first secret key to obtain a decrypted data segment; and then, displaying the decrypted data segments. The data file is encrypted in a segmented manner, so that the data file can be decrypted in a segmented manner, all data does not need to be loaded during online reading, and only the currently read content needs to be loaded and decrypted at the same time according to needs, so that the firstloading time is greatly shortened, and the reading efficiency is improved. Moreover, the length of the file is not changed by encrypting and decrypting each byte in an XOR manner, so that the purposesof the length of the file in various scenes can be reserved to the maximum extent.

Description

technical field

[0001] The present invention relates to the field of computer information processing, in particular to an information processing method, device and storage medium. Background technique

[0002] At present, in an online reading system, the chapter contents of novels or other books are stored locally in the form of files, or displayed by acquiring data from a remote server through a network. In this process, if it is transmitted or loaded in plaintext, the content is easily captured and the copyright cannot be effectively protected. However, commonly used encryption algorithms, such as Data Encryption Standard (DES), Advanced Encryption Standard Algorithm (Advanced EncryptionStandard, AES), RC4 encryption algorithm (Rivest Cipher 4), RSA encryption algorithm, etc.

[0003] However, using these algorithms will have the following problems: 1) The length of the original text will be changed, but this length may have special purposes in the system implementation, ...
