Abstract
An encryption method and apparatus is provided for increasing the security of encrypted data by puncturing or repeating a part of coded data. The data encryption method includes converting data to be encrypted using a certain encryption function; generating a codeword by performing ECC encoding on the converted data; puncturing a part of the converted data included in the codeword; interleaving the punctured data; and inserting errors to the interleaved data.
