A member of the Institute has participated in a work in the journal “Advanced materials” where creation of a true random number generation is proposed based in the stochastic properties of memristors’ workings. These new electronic devices present exceptional properties for applications related with non-volatile memories, neuromorphic computation and hardware cryptography.
Unlike memristors made with oxides of transition metals, which are more frequent, in this case it’s made of multilayered hexagonal boron nitrure. Using layers of this new material, which has a bidimensional structure, allows to develop technology for random number generation with a high level of randomness, even for long strings of bits, which are ideal for using in cryptography. In particular, its application is interesting for the production of one-use keys that can be used for safe payment methods with phones or for encrypted network connection or services in the context of “Internet-Of-Everything”. Memristors based in hexagonal boron nitrure have very low consumption, which allows to use them in portable applications where battery duration is essential.
