The white-box attack is a new attack context in which it is assumed that cryptographic software is implemented on an un-trusted platform and all the implementation details are controlled by the attackers. So far, almost all white-box solutions have been broken. In this study, we propose a white-box encryption scheme that is not a variant of obfuscating(More)
White-box cryptography (WBC) aims to resist attacks from attackers who can control all the implementation details of cryptographic schemes. In 2009, Saxena et al. proposed a fundamental of white-box cryptography via the notion “white-box property” (WBP). Under this model, they proved that there do not exist obfuscators that can satisfy every security notion(More)
Feistel structure is widely used in the design of block ciphers. With many Feistel-type ciphers being designed, it is likely for some of them to have some similarity which can be shown in their differential characteristics or linear characteristics. Noticing two Feistel-type ciphers, LBlock and TWINE, have the same number of impossible differential chains(More)
