It is more about spotting the handshake as you connect to a tor entry point, if that has a pattern to it, then that could be tracked even if entry points are random, the joys of DPI and pattern matching.

I was highlighting that use of Tor even without knowing what you are doing, could be seen as a sign of hiding something, that might be of interest.

On encryption, certain key levels and algorithms are considered secret, or have limited availability outside the USA and friends.

Another country that is not a police state, refused entry to the country based on a tweet someone made, so they are watching carefully, much more so than a UK ISP will be.

are you saying a country refused re-entry to one of it's citizens based on a tweet? If not then it's not the same.

I will look into the handshake for a Tor entry node as opposed to a standard vpn/https server. I admit limited knowledge here, but I see no reason for them to be different.

I can see the potential for packet frequency/size to be pattern-able for the next hop negotiation however (or for linking to the correct service on the entry node), that is an interesting line of reasoning. I would expect it is easy to add randomised obscuring traffic into the clients though.

My main point though, is even if my curtains are closed and i'm making interesting sawing hammering sounds, these are not reasonable grounds to force entry into my house to find out what I am doing. For sure, a policeman can knock on my door to ask, but I don't have to open it or tell him what I am doing. We have rights to privacy in law, and you will need some good evidence of crime or intended crime before a judge will give you a warrant that supercedes these rights.
Exercising your right to privacy does not mean you are doing illegal activity any more than exercising your right to free speech means what you say is a lie, or inflammatory.

Refused entry to a citizen from a foreign country...i.e. what you say online is pretty heavily followed.

In reply to a post by MrSaffron:

Am willing to bet that an ISP can easily identify who is using Tor, but not the traffic, and willing to bet it may be red flags issue, i.e. police/security services will assume you have something to hide.

If people don't like TalkTalk and its Malware spider system, best to change provider, but ensure that the next one never ever runs any of its kit in a debug mode.

Not so easy when you have moved onto an LLU system and Talk talk are the only provider in your area and you are locked into a 12 month contract with them, it would cost a bit to change provider now.

I have always been happy with their phone service, i'm just not convinced this spider won't be used for some other purpose in the future.

If it follows me into password protected areas then that is a concern too.

I have been with talk talk for nearly a year now. i didn't know about this spider thing. Service has been bad over the past few months and on top of that they are spying on me too. Defintelt not staying with talk talk anymore. Gonna look up for some alternative ISP Providers!!
