Robust User Authentication mechanism for Mobile DRM System Based on AES Algorithm
Jin-Oh Jeon, Min-Sup Kang · 한국정보기술학회논문지 · 2011
Owing to rapid advancement of telecommunications technologies, there have been many studies on contents protection based on various schemes in the field of mobile digital contents. Until now, contents protection has been focused on blocking piracy, issuance/management of authentication certificates, but there are still many vulnerabilities in terms of disclosure of classified information or authentication. This paper attempts to protect classified information on contents based on the redundant management of permissions for contents utilization via cellphone number or handset number. It also discusses the building of secure mobile digital right management (DRM) system at which digital contents would be distributed safely through triple user certification processes to protect replay-attack. And the paper discusses strengthening of security of contents based on the Advanced Encryption Standard (AES), an international standard encryption algorithm, in the processes of primary/secondary authorization processes for the sake of strong user certification to prevent piracy and to protect copyrights.
