Morning Call: pick of the papers

The ten must-read pieces from this morning's papers.

If not for Alfredo Astiz, 30 years ago Britain would have lost the Falkland Islands and Thatcher her political career, says Simon Jenkins.

2. Those hard Tory heads and hearts are back (Times) (£)

Not only is the 50p tax cut indefensible, but the Chancellor's cuts are grossly unfair in their effect on the poor, argues Philip Collins.

3. France is a deeply racist country, and Toulouse will only make that worse (Independent)

The French have transferred their resentments from Jews to Arabs, says Adrian Hamilton.

4. Chancellors cross the elderly at their peril (Daily Mail)

Osborne is blithely ignorant of the pain the elderly have suffered in the past few years, says a Daily Mail editorial.

5. Osborne gets bolder with each Budget - but it's still not enough (Daily Telegraph)

The Chancellor's slow-motion cuts are dragging out the austerity process, says Fraser Nelson.

6. A budget for Tory blowhards and Redwood dreamers (Guardian)

Forget mugging grannies, George Osborne's 50p rate gamble reveals a naked yearning for the glory days of Thatcher, writes Polly Toynbee.

The problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
