Abstract
Disclosed are an apparatus and method for public key encryption using a white-box cipher algorithm. An apparatus for public key encryption using a white-box cipher algorithm includes a key table generator configured to generate at least one key table from a cipher key, a hidden-key table generator configured to convert the at least one key table into at least one hidden-key table, and an encryption algorithm generator configured to generate a white-box implemented encryption algorithm by using the at least one hidden-key table and an inverse operation of the conversion and provide the generated encryption algorithm as a public key for encryption.
