摘要:
A data encoding apparatus for verifying data integrity by using a white box cipher includes: an encoding unit for encoding content by using a white box cipher table; and an arithmetic logic unit for performing an arithmetic logic operation on the white box cipher table and content information to output an encoded white box cipher table. The arithmetic logic operation is an exclusive OR operation. The content information is license information of the content or hash value of the license information of the content.
