Abstract
A method is provided for protecting a device against a side channel attack. In the method a portion of code in a program stored in read only memory (ROM) of an integrated circuit is determined to be vulnerable to a side channel attack. A patch memory is provided, separate from the ROM, for storing one or more instructions configured to transfer execution of the portion of code to a side channel protection function stored in the ROM. Execution of the program is transferred to the side channel protection function stored in the ROM. The side channel protection function in the ROM is configured to modify execution of the portion of code to protect against a possible side channel attack. After the side channel function is applied, normal program execution resumes. In another embodiment, an integrated circuit is provided that performs the method.
