If We Were To Create the Internet again … it would be Tor-based

Networking the proper way … Tor, Curve 25519 and ECDH

--

The Internet was NOT designed with integrated security, and where security was generally an after-thought. We needed to boot-up the Internet, and security was just not required when we created its infrastructure. And so virtually all our communications have since been flawed in some way, and where we use a sticking plaster of SSL. The proper way to do it — if we were to start again — is to encrypt the data at its source, and then use onion routing — Tor. At the core of Tor is ECDH (Elliptic Curve Diffie Hellman) and Curve 25519, and which gets its name from the prime number it uses for its calculations: 2²⁵⁵ — 19.

Tor routing

The Web traces a wide range of information, including user details from cookies, IP addresses, and even user behaviour (with user fingerprints). This information be used to target marketing to users, and also is a rich seem of information for the detection and investigation of crime. The Tor network has long been a target of defence and law enforcement agencies, as it protects user identity and their source location, and is typically known as the dark web, as it is not accessible to key search engines such as Google. Obviously Tor could be used to bind to a server, so…
