Toshiba Develops Chip Authentication Technology Using Transistor Noise

Toshiba has developed a new method of utilizing random telegraph noise (RTN) originating from insulating material faults to implement a physical unclonable function (PUF), an important security technology.

The method, which will contribute to the creation of safe and secure cloud services for smart communities, was announced at the VLSI Technology Symposium, a conference on semiconductor devices that was held on June 16 in Kyoto, Japan.
