- Digital Rights Management (DRM)
- Purpose: DRM uses encryption to enforce copyright restrictions on digital media, ensuring that digital content is used in accordance with copyright laws.
- Legal Framework: DRM is part of the effort to bring U.S. copyright law into compliance with the terms of two World Intellectual Property Organization (WIPO) treaties.
- DMCA (Digital Millennium Copyright Act):
- Provision: The first major provision of the DMCA is the prohibition of attempts to circumvent copyright protection mechanisms placed on a protected work by the copyright holder.
- Cryptographic Algorithms
- RC4: A stream cipher commonly used in various encryption protocols.
- RC5 and RC6: Block ciphers, with RC6 being an improved version of RC5, both of which are used in encryption processes requiring block ciphers.
- FIPS 140
- Definition: Federal Information Processing Standard (FIPS) 140 outlines the hardware and software requirements for cryptographic modules, ensuring that they meet specified levels of security.
These concepts are critical for understanding how digital content is protected through legal and technical means, particularly in the context of copyright enforcement and the use of cryptographic algorithms.
