Wi fi wow & tech question
Oct. 15th, 2008 01:06 pmFollowing recent discovery of wi fi on Oxford to Heathrow coach, have now discovered it is available and FREEE on Edinburgh to London Nat Express train. Whoopee! I may never fly again :-)
Going over stuff for data retention thing tomorrow. Utter confusion appears to rule. Any No2ID niks out there know more? El Reg says Intercept Modernisation all-data -in-one-place db is to be dropped from Communicataions Data Bill. But Indy, today, carries front page saying opposite. wah. Oh well I can ask Home Office and HL direct tomorrow!
Ok, question for techies. Suppose an ISP retains data froma Skype VOIP trasmission, was told at conf a few weeks back by Skype person that that data is encrypted and Skype don't have the key. So is tere any point in collecting that data? Could it be taken to recipient of call and key demanded? Or does recipient merely see plain text and not have key either? (This seemed to be how I recakll Skype - tho it was long time ago.)
What I'm getting at here, is what's the point of retaining data no one can decrypt?
Also when your current traffic - say email or Skype, whatever - goes through networks, and the traffic data is retained for billing purposes, what kind of security is applied to the storage of that data? Is there an industry standard?
Also, I'm told there are c 400 ISPs in UK but only 6 carry 90% of traffic. Many of the others essentially simply buy bandwidth wholesale from BT. Anyone have any idea how many ISPs actually have own non BT lines?
