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.

摘要： A group signature system includes: a key issuer server for generating a first parameter of a group public key, generating a corresponding master issuing key, and issuing a signature key to a user when a user device joins; an opener server for generating a second parameter of the group public key, and a corresponding master opening key and master linking key; and a linker server for checking whether two valid signatures have been linked by using the master linking key when the two signatures corresponding to a group public key are given. The group signature system further includes: a signature verifying unit for confirming a validity of the given signatures and a signer information confirming unit for confirming a validity of singer confirming information generated by the opener server.
