Abstract: An apparatus and method for providing a security service are provided. The apparatus for providing a security service includes a first block cipher and a second block cipher. The second block cipher is independent of the first block cipher, and is configured to be used as a random number generator when the first block cipher is used to perform encryption/decryption, and to be used to perform encryption/decryption when the first block cipher is used as a random number generator.
