Abstract: Disclosed is a function masking apparatus in a symmetric cryptographic algorithm for preventing side channel attacks, including: a controller creating lookup tables for one or more internal functions included in a high security and light weight (HIGHT) algorithm, respectively based on a plurality of non-linear functions, a plurality of linear functions, and a plurality of constants which are randomly generated; and a storage unit storing the lookup tables for one or more internal functions included in the generated HIGHT algorithm.
