Abstract

We investigate the possibility to use obfuscated implementations of the Advanced Encryption Standard AES (“white-boxed AES”) to devise secure signature schemes. We show that the intuitive idea to use AES-based message authentication codes to sign, and the white-boxed implementation to verify, fails in general. This underlines that providing a secure white-box implementation is only the first step and that using it securely as a component in cryptographic protocols may be harder than originally thought. We therefore provide secure signature schemes based on white-boxed AES and on random oracles, as well as stateful and stateless constructions without random oracles. All our solutions are shown to be secure for reasonable parameters.
