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.
PUFs contribute to improved security technologies for encryption and authentication by using a chip's "fingerprint", a unique identifier resulting from variations in the devices in an electronic circuit. PUFs are attracting attention because they secure a high degree of unclonability at a low cost.
