Abstract
Stochastic or near-stochastic physical characteristics of resistive switching devices are utilized for generating data distinct to those resistive switching devices. The distinct data can be utilized for applications related to electronic identification. As one example, data generated from physical characteristics of resistive switching devices on a semiconductor chip can be utilized to form a distinct identifier sequence for that semiconductor chip, utilized for verification applications for communications with the semiconductor chip or utilized for generating cryptographic keys or the like for cryptographic applications.
