Developed a new architecture for a computer processor that independently resists potential security threats by continuously encrypting and randomly rearranging key bits of its own code and data.
Existing methods of fighting cyber attacks are based on additional software, but breaking it is only a matter of time and resources. The problem is becoming more significant due to the development of the Internet of Things, unmanned vehicles and other digital technologies. Therefore, engineers from the University of Michigan have developed an innovative MORPHEUS chip that stops any known types of attacks. even before they start.
The new architecture transforms data 20 times per second, so even the most advanced hacking systems will not have time to find vulnerabilities. Moreover, if a hacker finds a loophole, then after 50 milliseconds it automatically disappears. Conversion frequency can be modified to achieve an optimal balance between safety and resource consumption.
During the demonstration, just such a frequency was chosen, because it is a thousand times greater than the capabilities of the fastest electronic hacking methods, but reduces productivity by only 1%. The architecture also includes an attack detector that identifies potential threats and increases the bit randomization rate if suggests an imminent attack.
The developers compare MORPHEUS with a Rubik’s cube, which rebuilds after each blink, turning into an insoluble problem. In the chip, this is due to features of undefined processor semantics.
The study was funded by the Defense Advanced Research Projects Agency. After successfully demonstrating the open source chip, the team began working on commercializing the technology through startup Agita Labs..
We also previously reported about creation of a prototype of ultra-fast laser Wi-Fi.
