Abstract:
A method for generating a random number, comprising steps of receiving a data transmission binary signal subjected to phase jitter, generating several oscillator signals substantially of a same average frequency and having distinct respective phases, sampling a status of each of the oscillator signals upon the appearance of edges of the binary signal, and of generating a random number using the statuses of each of the oscillator signals. The method may be applied to an integrated circuit usable in a smart card.
