Abstract

The present invention relates to an image forming apparatus, a data processing method and a computer readable recording medium. The disclosed image forming apparatus includes a storage unit (21) storing cryptographic data related to a cryptographic function; a first recording unit configured to obtain the cryptographic data from the storage unit and record the cryptographic data in a first storage area (22) that can be referenced from the plural program execution environments; and plural second recording units provided in the plural program execution environments and configured to obtain the cryptographic data from the first storage area and record the cryptographic data in a second storage area for each of the plural program execution environments so that the cryptographic data can be referenced by the program executed in the plural program execution environments.

Description

technical field [0001] The present invention relates generally to an image forming apparatus, a data processing method, and a computer-readable storage medium, and more particularly, to an image forming apparatus, a data processing method, and a computer-readable storage medium each having an encryption function. Background technique [0002] In recent years, there have been image forming apparatuses such as printers, copiers, and multifunction peripherals that are equipped with a Java (registered trademark) virtual machine (VM) and can execute programs distributed in Java bytecode. However, a virtual machine has limited storage space available. Therefore, in some cases, it is necessary to form a plurality of virtual machines in order to realize a plurality of functions of an existing image forming apparatus. Furthermore, in some cases it is also necessary to guarantee the execution of applications written in traditional code, ie, known as native code. In such an image for...
