CONTENT ENCODING METHOD, CONTENT DECODING METHOD AND ELECTRONIC DEVICE USING SAME

摘要

A method for encrypting a content, a method for decrypting a content, and an electronic apparatus applying the same are provided. The method for encrypting complexly encrypts a content by complexly applying a plurality of encrypting schemes to a single content. Accordingly, a means for encrypting digital contents is reinforced. Also, a hacked key list stored in an electronic apparatus is updated with reference to a hacked key list externally received. Accordingly, a means for authenticating an apparatus which requests contents is reinforced.
