Study on E-Paper Controller Integrated with DRM

Abstract

Security vulnerabilities and the slow speed of traditional Digital Rights Management (DRM) in E-Paper device are the major restrictions of E-Paper industry. This paper introduces a new type of E-Paper controller which is integrated with DRM. DRM is realized in hardware. Data stored in main memory and controller memory or transferred from CPU to controller are encrypted. So that so they are more secure. Display process and decryption process are combined into one pipeline and can run simultaneously. Thus higher speed and less security vulnerabilities are given to controller.
