Earlier this year, the British prime minister David Cameron spoke against allowing Internet users to encrypt their traffic, thereby avoiding government surveillance. On this issue, the Parliamentary Office of Science and Technology (POST) has prepared detailed report In the document, the service explains to policymakers what Tor is and what they will face if a decision is made to block it.
The report explicitly says that Tor blockades are technically very difficult to enforce. Even in China, with its canonical "Great Firewall, " Tor continues to work through a system of so-called "bridges" designed specifically to circumvent blocking. And while some attempts by the intelligence services to track down users of the network have been successful in the past, it has often been due to user error rather than problems with anonymity on the network itself.
In addition, the report informs why banning Tor doesn’t make political sense. For example, the problem of pedophiles, the fight against which is now at the height of popularity among governments of all kinds, in Tor exaggerated – according to the report, such sites account for no more than 2% of all "dark Internet" resources. This may be due to the fact that Tor is not designed to transmit large amounts of information.
In passing, the report also mentions i2p networks (a hidden resource network without access to the normal Internet) and FreeNet (an anonymous distributed sharing and storage network). But these networks are much less popular and therefore their impact is not even considered at the highest level yet.
Unfortunately, POST is not an influential entity, and its report can only be considered as one factor in the final decision. Whether Cameron will want to change his attitude toward encryption is still a big question.
