Abstract (en)

[origin: WO0241151A1] The invention concerns a device for making secure electronic devices against attacks (for example lateral path attacks) during the processing of sensitive and/or confidential data by a central processing unit (CPU) to a volatile storage (for example the RAM) of an electronic device such as, for example, a smart card, a PDA or a cellular telephone. The method consists in storing confidential data to a storage site dynamically and randomly allocated, thereby making analysis more difficult and, consequently, attacks (for example lateral path attacks).
