Abstract

Digital rights management (DRM) is crucial in safeguarding digital content in today's digital era. However, with the advancement of attack techniques, DRM systems face significant threats from key exposure, leading to increased piracy. To counter this, various DRM solutions utilizing white-box encryption schemes have been developed to prevent key exposure. Unfortunately, many existing solutions exhibit security vulnerabilities, compromising their robustness. Other solutions, while secure, suffer from limited efficiency and high memory costs, rendering them unsuitable for managing the vast amounts of digital content prevalent today. In this paper, we propose a robust and cost-effective DRM solution based on a novel white-box encryption... (More)

Digital rights management (DRM) is crucial in safeguarding digital content in today's digital era. However, with the advancement of attack techniques, DRM systems face significant threats from key exposure, leading to increased piracy. To counter this, various DRM solutions utilizing white-box encryption schemes have been developed to prevent key exposure. Unfortunately, many existing solutions exhibit security vulnerabilities, compromising their robustness. Other solutions, while secure, suffer from limited efficiency and high memory costs, rendering them unsuitable for managing the vast amounts of digital content prevalent today. In this paper, we propose a robust and cost-effective DRM solution based on a novel white-box encryption scheme. Our theoretical analysis demonstrates that the proposed solution effectively resists key recovery attacks on the server side, as well as key extraction and code lifting attacks on the client side. Experimental validations further reveal that our solution surpasses existing methods in processing efficiency and memory usage. Notably, decryption achieves speed-ups of up to 831 times and 400 times on Intel central processing units compared to SPACE-32 (CCS'15) and HOUND-32 (ASIACRYPT'16), respectively.
