I cannot understand why the government is going through with the RIP Bill. It is so technically inept

It also gives them the power to demand encryption keys so they can unlock any scrambled data they intercept or find on seized computers.

But the authors of the FIPR report say it is easy for the computer-literate to avoid the attentions of the security forces and keep data private.

"We have been saying for a long time that it is trivially easy to get round the technology provisions in the Bill," said Mr Gladman, a former director of the Nato technical centre. "I cannot understand why the government is going through with the RIP Bill. It is so technically inept."

Criminals catch up

Rather than stop criminals using the net, the methods outlined in the RIP Bill will "undermine the privacy, safety and security of honest citizens and businesses", says the report.

News of the report appeared first in New Scientist.

As one example, Mr Gladman said it was easy to stop e-mail messages being intercepted by using an offshore e-mail account that encrypted messages as they moved across the net.

The report also mentions that the new version of the Internet Protocol will make it much harder to intercept data. The protocol allows two internet-connected computers to use encryption keys that are destroyed after each exchange of data.

Protecting e-mail

Use an offshore e-mail service Encrypt when sending and receiving Send messages direct to recipients Use software that supports IPv6

The advent of "always-on" technologies such as ADSL might remove the need for a mail server that holds mail until you download it, said Mr Gladman. People may start to send messages direct to each other, making it much more difficult for them to be caught in flight.

Mr Gladman said that although there were many ways for people to avoid the attentions of the security forces, many of them demanded technical knowledge to set up and use.

Criminals will be prepared to invest the time and energy to learn how to use software or techniques that can help them avoid arrest but others may be left vulnerable.
