Data processing method and related equipment

Abstract

The embodiment of the invention discloses a data processing method and related equipment, which are used for saving storage space. The method comprises the steps of obtaining an original character string and a target displacement amount, wherein the original character string comprises a plurality of original characters arranged in sequence; encrypting each original character by using the target displacement to obtain an encrypted character corresponding to the original character; arranging the plurality of encrypted characters according to the arrangement sequence of the original characters in the original character string to obtain an encrypted character string; when the encrypted character string has a segment of characters continuously formed by a plurality of identical encrypted characters, the identical segment of identical encrypted characters are replaced by an identical encrypted character and a special character, a compressed character string is generated, and the special character is used for representing the continuous occurrence frequency of the encrypted characters in the same segment.

Description

technical field [0001] The embodiments of the present application relate to the computer field, and in particular, to a data processing method and related equipment. Background technique [0002] Encryption and decryption of software is a fascinating field of study that can be closely integrated with almost any kind of computer technology—cryptography, programming languages, operating systems, data structures. The existing commonly used encryption technology is symmetric encryption, which uses symmetric cipher coding technology, and its feature is that the same key is used for file encryption and decryption, that is, the encryption key can also be used as the decryption key. In science, it is called a symmetric encryption algorithm. The symmetric encryption algorithm is simple and quick to use, the key is short, and it is difficult to decipher. Data encryption standard (DES, data encryption standard) is a kind of symmetric encryption technology. [0003] Now the string is ...

[0004] However, using the DES algorithm to encrypt will increase the length of the string. Even if the encryption is completed and then compressed using the GZip algorithm, the length of the string will exceed the original length. In fact, after the encryption and compression are completed, the length of the string will increase.
