The invention relates to a method comprising two steps. The first step involves classifying the static memory cells into two discrete sets according to their behaviour towards repeatedly being connected to a power supply after having been with out a power supply for a sufficient period of time, such that the cells of one of the sets are suitable for generating identifiers (key or secret) and the cells of the other set are suitable for generating truly random numbers. Thanks to this classification, in the second step, involving the generation of numbers, the identifiers and the random numbers generated perform better. The invention also relates to a device for carrying out the method according to the invention, said method being carried out by adding very simple circuitry to the memory or running very simple software. The scientific-technical fields of the invention are those of cryptography, electronic technology, security and privacy. |
