Close encounter

Sunday, June 26th, 2011

Impossible to spot with the naked eye, but exciting enough to make you want to look up at the sky tomorrow. To give you an idea on how close to earth this is, it will pass through the zone of geosynchronous satellites!

Paper on hardware security attacks

Saturday, June 25th, 2011

Interesting and extensive read. A very short abstract:

This thesis presents a wide range of attacks on hardware security in microcontrollers and smartcards. This includes already known non-invasive attacks, such as power analysis and glitching, and invasive attacks, such as reverse engineering and microprobing. A new class of attacks – semi-invasive attacks – is introduced. Like invasive attacks, they require depackaging the chip to get access to its surface. But the passivation layer remains intact, as these methods do not require electrical contact to internal lines. Semi-invasive attacks stand between non-invasive and invasive attacks. They represent a greater threat to hardware security, as they are almost as effective as invasive attacks but can be low-cost like non-invasive attacks.

The paper is already 6 years old, but well worth a look; Semi-invasive attacks – A new approach to hardware security analysis

Make a radical change in your lifestyle and begin to boldly do things which you may previously never have thought of doing, or been too hesitant to attempt. So many people live within unhappy circumstances and yet will not take the initiative to change their situation because they are conditioned to a life of security, conformity, and conservation, all of which may appear to give one peace of mind, but in reality nothing is more damaging to the adventurous spirit within a man than a secure future. The very basic core of a man’s living spirit is his passion for adventure. The joy of life comes from our encounters with new experiences, and hence there is no greater joy than to have an endlessly changing horizon, for each day to have a new and different sun. If you want to get more out of life, you must lose your inclination for monotonous security and adopt a helter-skelter style of life that will at first appear to you to be crazy. But once you become accustomed to such a life you will see its full meaning and its incredible beauty.
