A Study on Encrypted Matrix Puzzle for Digital Contents Protection

디지털 컨텐츠 보호를 위한 메트릭스 퍼즐 암호화방법에 대한 연구

  • Published : 2008.08.31


DRM system is a technology that protects and manages copyright holder's privilege by using a copyright protection technology. This paper contributes to improvement of the secret key transmission and encryption/decryption processing time base on DRM system. In this paper, we will suggest that as follow: First, we will propose the algorithm to transmit the encryption key which use Multidimensional Method more safe than the existing One-path XOR method. Second, we will provide the high quality algorithm of security than the existing system because the Multidimensional which generated from the algorithm does not saved to the server side. Third, we will support the client decryption system which can decrypt the Multidimensional with OPT in decryption with client side. Fourth, we will adopt the more safr method of transmission with the compound of Multidimensional Method and OPT.
