Abstract
A multi-party system, devices, and method for token-based obfuscation of secret information. A first party device may store a secret original program T and original data D, retrieve a set of secret keys SK, obfuscate the original program T with the set of secret keys SK to generate an obfuscated program T', obfuscate the original data D with the set of secret keys SK to generate a token of the data Token(D), and transfer the obfuscated program T′ and Token(D) to a second party device. The second party device may evaluate the obfuscated program T′ on the token of the data Token(D) to generate a result equivalent to evaluating the original program T on the original data D if the same set of secret keys SK is used to obfuscate the original program T and the original data D, without exposing the original program T to the second party.
