The processor with the system of random changes in the microarchitecture could not hack


For four months, more than 500 hackers were unsuccessfully tried to hack the Morpheus processor, which randomly rebuilds its microarchitecture 20 times per second.

In any software, there are errors and vulnerabilities that allow attackers to hack it. Developers regularly correct them when detected, but it often happens after a hacker attack. However, this does not stop hackers who simply find another breach in defense. Such cyclic opposition leads to a continuous arms race between hackers and developers.

Since to introduce malicious code, the attackers need to determine the chip microarchitecture, the researchers from the University of Michigan have developed a new type of computer processor, which can block any attempts to hack at the hardware level before the start of the attack.

Created by them chip

Recently, the management of promising research projects of the US Department of Defense conducted a number of innovative processors. As part of the program, 535 professional special researchers were involved in computer security researchers. For 4 months, none of them could find a way of hacking Morpheus.

In this case, the battling system does not affect the operation of users and developers. The only side effect is a 10 percent reduction in speed compared with the same processor power. The team plans to solve this problem by refineing the system.
