1. Immutable Content Naming: In a data-centric system, content is addressed by its name, transcending geographical considerations. This circumvents the vulnerabilities associated with IP addresses, which can be spoofed or manipulated. By employing cryptographic techniques to validate the authenticity of content names, NDN establishes a robust layer of security that underpins the entire architecture.
2. Built-In Data Integrity: NDN employs built-in mechanisms to ensure the integrity of data. Content is signed by publishers and verified by consumers, preventing tampering or unauthorized alterations. This approach effectively mitigates data breaches, as any unauthorized modification is detected and rejected.
> NDN has its roots in an earlier project, Content-Centric Networking (CCN), which Van Jacobson first publicly presented in 2006.. NDN applications name data and data names will directly be used in network packet forwarding.. Its premise is that the Internet is primarily used as an information distribution network, which is not a good match for IP, and that the future Internet's "thin waist" should be based on named data rather than numerically addressed hosts.
