Abstract: | At CMS 2006 Bringer et al. show how to conceal the algebraic structure of a ``traceable block cipher'' by adding perturbations to its description. We here exploit and strengthen their ideas by further perturbing the representation of a cipher towards a white box implementation. Our technique is quite general, and we apply it -- as a challenging example in the domain of white box cryptography -- to a variant of the block cipher AES. |
