In order to protect AES software running on untrusted platforms, Chow et al. (2002) designed a white-box implementation. However, Billet et al. (2004) showed that the secret key can be extracted with a time complexity of 2. In this paper, we present an improved whitebox implementation of AES. We use dual ciphers to modify the state and key representations in each round as well as two of the four classical AES operations, SubBytes and MixColumns. We show that, with 61200 possible dual ciphers… CONTINUE READING
