Patent

CA 2326036

A method for securing electronic device processes against attacks (e.g. side channel attacks) during the processing of sensitive and/or confidential data by a Central Processing Unit (CPU) to the volatile memory (e.g. RAM) of an electronic device such as, for example, a smart card, a PDA or a cellular phone is described herein. The method involves the storage of the confidential data to a dynamically and randomly assigned memory location, thereby rendering more difficult the analysis and subsequently the attacks (e.g. side channel attacks).
