Side-channel attacks are a real threat, exploiting and
revealing the secret data stored in our electronic devices just
analyzing the leaked information of the cryptographic modules
during their normal encryption/decryption operations. In this
sense, electromagnetic attacks have been posed as one of the most
powerful attacks, retrieving the secret information by analyzing
the existing relation between the leaked electromagnetic radiation
and the data being processed. These attacks are known as
ElectroMagnetic (EM) attacks and a extremely critic point for
their success is the EM probe positioning. In this paper, an
automated experimental setup for EM cartography is described
to enhance EM attacks and to help hardware designers to detect
the possible information leakage flaws, as well as to determine the
security level reached by the hardware implementations against
EM attacks
