ScienceDaily (February 8, 2011) product that increasingly target electronic chips and components, with attacks on hardware modules becoming commonplace. Custom security technology takes advantage of the features at the individual element to create a digital key. This provides the elements with the same--because you cannot copy the their unique structure.
Fraunhofer Institute researchers have display prototype worldwide embedded at Nuremberg Exhibition & Conference from March 1 to 3.
Product piracy is a long time ago is limited exclusively to a consumer goods sector. Too, the industry, there are more and more to fight this problem. Cheap mkosmim: Dear business cost the German mechanical and plant engineering alone lost 6.4 billion of revenue in 2010, according to a survey by the German engineering Federation (VDMA). Sales losses aside, low-quality counterfeits can break even the image of the company's brand. Worse, they can even compromise the life of the people if they are used in areas where safety, such as the production cars or airplanes. Patent rights or organizational instructions such as confidentiality agreements will not be enough to prevent product piracy. Anti-piracy technology that exists in today's marketplace provides a measure of protection, but it is an obstacle to the product and more for you: criminals are using the electron microscope, laser focused ion beams or bolts to intercept security keys-and baimotz more and more sophisticated methods.
Two chips are not
Embedded world, researchers at the Fraunhofer Institute sit secure information technology electronic components be ricot or chips can do counterfeit-proof using physical unclonable functions (PUFs). "Each element has a single fingerprint since small differences inevitably arise among during production," explains Dominik mrli, scientist at the Fraunhofer Institute sit in Garching near Munich. Printed circuits, for example, at a minimum weight or length variations during the manufacturing process. While these variations do not affect functionality, they can be used to create a unique code.
Destroying the structure polshni attacks
PUF module, integrated directly into chip-Setup is applicable not only in a large number of half-molichim programmable called FPGAs (field programmable gate arrays) but equally hardware components, such as ??????? and smartcards. "The heart is a circle measure, e.g. a ring oscillator. This creates a clock oscillator characteristic that allows precise material features of the chip set. Special electronic circuits to read these and generate measurement data from the data, developing a specific ???"????? mrli. Unlike the standard encryption, secret key is not stored in hardware but this threshold as and when required. Since the code relates directly to a given system properties at any point in time, it is almost impossible to extract and to replicate it. Polshni chip you target, and physical change parameters or distort the unique structure.
Garching-based researchers have developed already two fathers are: butterfly, PUF PUF ring vmd. At present, these modules are optimized for practical applications. The experts will be at embedded world at Nuremberg (Hall 11, stand 207) from 1-3 March example example FPGA boards can generate a single encryption key by using ring oscillator PUF. These allow security solutions-embedded systems rolled out attack.
