Methods for encoding digital control files in sewing processes

Abstract

The term refers to a method of encrypting data in a digital process control file using a multi-key cross-combination encryption method to encrypt file data. First, the first level of encryption is performed, obtaining the key and mask of the standard data header and instruction content, and encrypting the standard data header and instruction content accordingly. Next, a second level of encryption is performed, applying AES encryption on top of the first level of encrypted data, enhancing the encryption strength of the data content, and finally generating and exporting an xdg file. The xdg file contains the original data format converted into machine process data, including the user's default commands, custom commands, and the original needle data format. The primary method used to support the correction process is to prevent secondary distortion and ensure the integrity of the graphic data.
