APPARATUS AND METHOD FOR CONTENTS ENCRYPTION AND DECRYPTION BASED ON STORAGE DEVICE ID

摘要

Provided are a method and an apparatus for encrypting and decrypting content, capable of preventing encryption content from being illegally copied to other storage apparatuses. The present invention relates to a content recording apparatus comprising: a storage apparatus interface for receiving a first primitive ID and a second primitive ID for identifying a first part and a second part included in a storage apparatus respectively from the storage apparatus; and a processor for generating a media ID, which is the identifier of the storage apparatus, using the first primitive ID and the second primitive ID and for encrypting content with a generated encryption key using the media ID. The storage apparatus interface provides the content encrypted by the processor to the storage apparatus.
