Abstract : True random number generators (TRNGs) are significant piece of hardware security that are used to generate secret keys, initial values or random masks for counter measures against side-channel attacks. Thus the security of implementation in hardware of such block is crucial. The work presented in this paper show that it is possible to find information on a TRNG using its electromagnetic radiations. The proposed analysis is suitable to retrieve information on the localization, oscillator frequency and sampling frequency of the TRNG.
