Abstract
Provided is a method, performed by a device, of protecting information from a side channel attack, the method including: loading a library shared by at least one application installed in the device to a memory of a first layer; inputting a value to a function of the library; based on the value being input, detecting a region of the memory accessed by the device from among regions of the memory of the first layer, to which the library is loaded; generating a protection code which accesses regions of the memory other than the detected region from among the regions of the memory of the first layer, to which the library is loaded; and adding the protection code to the function of the library.
