Abstract
Disclosed is a dual conversion apparatus for preventing a side channel analysis, including: a microcontroller which converts one-bit expression, which is expressed by zero and one, into one of two four-bit transitions, reconstructs a cryptographic algorithm, and applies the four-bit converted dual conversion to the reconstructed cryptographic algorithm; and a storing unit which stores the four-bit converted dual conversion which is converted by the microcontroller.
