One of the main security challenges white-box cryptography needs to address is side-channel security. To this end, designers aim to eliminate the dependence between variables and sensitive data. Classical countermeasures to do so are masking schemes. Nevertheless, most masking schemes are not designed to thwart the other main security threat : fault attacks. Thus, we aimed to build a masking scheme that could combine resistance to both of these types of attacks. In this paper, we present our new generic fault resistant masking scheme using BCH error-correcting codes, as well as the design choices behind it.
