Private Internet

The article discusses the inadequacies of existing internet protocols, particularly in terms of security and privacy. Many protocols were developed in an era of implicit trust, which is no longer applicable due to the prevalence of malicious actors online. While IPv4 and IPv6 are generally considered well-designed, they still exhibit fundamental flaws, particularly concerning privacy and susceptibility to Denial of Service (DoS) attacks. The author emphasizes the need for a new network protocol that addresses these issues, proposing features such as non-sensitive client addresses, DoS resistance, and the prevention of outgoing and incoming connection address leaks. The article also suggests potential implementations, including onion routing and fine-grained routing, while acknowledging the challenges associated with these methods. The author concludes that while encryption is desirable, it may be better managed at a higher layer due to the slow evolution of fundamental protocols. Overall, the piece serves as a call to rethink and redesign internet protocols to enhance security and privacy in the current digital landscape.

- Existing internet protocols were designed without modern security considerations.

- IPv4 and IPv6 have fundamental flaws related to privacy and DoS attacks.

- Proposed features for a new protocol include non-sensitive client addresses and revocable connections.

- Potential implementations discussed include onion routing and fine-grained routing.

- Encryption is recommended at higher layers due to the slow evolution of core protocols.
