Securing Digital Content: Cryptography in DRM – Digital Rights Management.

Cryptography in DRM.
Encryption technologies serves as the foundation of Digital Rights Management (DRM), providing the essential mechanisms that regulate how electronic media is accessed, copied, and distributed. Its role directly supports copyright protection by enforcing permission management, preventing unauthorized duplication, and supplying verifiable evidence in infringement disputes.

Content Protection
• Encryption renders media unreadable without keys.
• Publishers manage access via decryption tokens.
Encryption ensures only authorized users can access digital media, maintaining exclusivity and preventing unauthorized use of copyrighted works through secure key-based control systems.

Privilege Control
• Asymmetric cryptography secures user licenses.
• Keys restrict playback to authorized devices.
By linking decryption privileges to users or hardware, DRM systems limit unauthorized sharing, ensuring that only verified customers can access purchased or licensed digital content.
