The Government wants our encryption keys. Are home keys next?

The just released report by 13 well known cryptographers opposing the US and British governments’ sweeping demand for encryption keys has directly addressed the increasing threat of government’s insatiable thirst for power. Any government objection to this report is bound to be disingenuous.
However, there’s one more angle that begs for further exposure. The overall issue is not a scientific or technical question; it’s an ideological one. The frequently heard loud claim that inevitably we have to give up our privacy so the government can protect us is flatly untrue and hypocritical. It is indeed technologically feasible today to build a system where everyone of us would wear an irremovable collar equipped with cameras, microphones, and GPS that would communicate our location and immediate surroundings every instant “totally securely” to some highly trusted government agency. The government may argue that a) it would only access this information upon some court order; and b) it would solve a lot of crimes and save a lot of lives. True, such a system would make the police’s job very easy, would solve a lot of crimes, and save a lot of lives. But the real question is: do we want to live in that kind of society? In the American spirit the politest answer would be, “Hell, no!” And as always with this kind of hypothetical system criminals would quickly find a solution to neutralize it, leaving us with the situation that only-law abiding citizens would be subject to this massive electronic prison.
Even as we see deeper and deeper assaults on our civil rights and liberty in the manner described above, the government is more than a little shy talking about other intelligence-gathering techniques that require more skill than a slightly trained operator just pushing a few computer keys. These methods are well known among professionals, they have existed for a long time, and can be applied to any target. The drawback of course is that they are less convenient for the operators, require greater skills, and do not include a global bulk collection of information on everyone.
Well, maybe this is just what we, the people, need and want.

Power grid: when cyber lines cross

We have very little time to cure our stone age cyber defensive technology.
The CNN story citing testimony by Admiral Michael Rogers, head of U.S. Cyber Command, to a House Select Intelligence Committee November 20 sounded like shocking news. He stated that China can take down our power grid.

Shocking as it may be, if this is still “news,” surprise, surprise — it’s been known to everyone who was anyone in cyber security for over 25 years. First it was just the Russians, then the Chinese, then some vague criminals acting on behalf of “nation-states” were gradually added to the list.
Never mind the Russians and the Chinese – they also both have enough nuclear weapons to kill every squirrel in America. What is really troubling is the cyber security trend. Our cyber defensive capabilities have hardly improved for over a quarter-century. However, hackers’ attacking capabilities are improving constantly and dramatically. This is not a good equation — sooner or later these lines will cross. This means that a large number of unknown hackers will be able to take down our power grid and also decimate our power-intensive facilities, such as oil refineries, gas distribution stations, and chemical factories.
Now, think terrorists. They would be delighted to do exactly that, whether you kill them afterwards or not. This isn’t news, but it’s an increasingly troubling reality. We have very little time to cure our stone age cyber defensive technology. But that requires changing the current equation and making cyber defense inherently more powerful that the offense. That won’t happen until the doomed legacy password and firewall paradigms are abandoned and replaced by fundamentally different technologies.
