South Korea has developed a unique security string NEM-PUFs chip

In the commercial and military fields, it has always been a very important thing not to let sensitive information fall into the wrong hands, but we are impressed by a solution proposed by Korean researchers. According to Inverse, The team created a device called NEM-PUFs, which is similar to having a unique fingerprint built into each chip in a computer, making it almost impossible to identify copy.

A NEM-PUF module occupies a very small area, during the manufacturing process, which suspends a silicon nanowire in the liquid of the two gates. When the liquid evaporates, the nanowires are randomly attached to one of them 'Door' (representing 0 or 1).

By combining these chips, you get a fairly long list of 'security codes' that are completely random and are said to be almost impossible to copy.

The researchers also tested the hardware in harsh environments and subjected them to high levels of radiation, microwaves, and high temperatures, and even added a self-destructing mechanism to destroy chips or equipment when tampered with.

As a result, it is clearly appealing to those organizations that need a secure solution, and details of the study have been published in the recently published ACS Nano, Journal.
