Abstract
Disclosed are a method and a device for compressing and decompressing unit files when encrypting an electronic publication (EPUB) file. The method for compressing unit files for EPUB file encryption comprises: a step of determining an encryption target unit file from among a plurality of unit files forming an EPUB file; a step of performing encryption of the compressed encryption target unit file; and a step of performing compression of general unit files among the plurality of unit files in addition to the encryption target unit file. As such, by performing compression of the encryption target unit file before the general unit files, it is possible to effectively reduce the size of a single packaged EPUB file.
