The Feasibility of Encrypting a Section of the Internet

The concept of encrypting a section of the internet has been debated among cybersecurity experts, but the reality is that it poses significant obstacles. For instance, ransomware attacks, which involve the encryption of user data, have escalated in scale and frequency, affecting millions of devices worldwide. While these attacks target individual or organizational endpoints, the broader question remains: can we meaningfully encrypt specific parts of the internet, and if so, would it even be feasible?

Understanding the Technical Challenge

When we talk about encrypting a section of the internet, we are referring to encrypting communications links between pairs of devices. This process would be highly cost-intensive, with no additional security benefits. The key security measures, such as end-to-end encryption, are already in place for most web traffic, email, and streaming media. For stored content or media, encryption is performed by the systems holding the data, not directly by the internet itself. This is a critical distinction that underscores the impracticality of encrypting the internet infrastructure.

Cost and Maintenance

Each connection on the internet involves multiple entities, including users, servers, routers, and telecom providers. Encrypting the connections between these points would require significant investments in both hardware and software. Telecom providers would need to upgrade their infrastructure, leading to substantial costs. Moreover, these costs would be spread across all users, regardless of whether they benefit from additional encryption.

End-to-End Encryption as the Optimal Solution

Instead of encrypting the internet infrastructure, which would be costly and have minimal benefits, the focus should be on end-to-end encryption. End-to-end encryption ensures that data remains secure during transmission from its origin to its destination, whether it's an email, a web message, or a video stream. This approach has already been adopted by many popular web services and is continuously improving to protect user data.

The security of stored content is managed by the systems hosting the data. These systems are not directly connected to the internet and are further protected by hosting site networks and their internet service providers (ISPs). For example, financial records or copyrighted media for streaming are encrypted at the hosting level, ensuring that the data remains secure while not being directly exposed to the internet.

There are several companies and organizations working towards enhancing internet security. For instance, cloud providers like AWS and Google Cloud offer robust encryption solutions that ensure data security at both the endpoint and while in transit. This approach is more effective and sustainable than attempting to encrypt the entire infrastructure of the internet.

In summary, while the concept of encrypting a section of the internet may seem appealing, it is impractical and costly. Instead, the focus should be on enhancing end-to-end encryption to provide the best possible security for user data. Current security practices, including those used for stored content, demonstrate that the internet can be protected effectively without the need for extensive infrastructure modifications. By leveraging existing technologies and continuous improvements in security, we can achieve better protection for our digital assets.
