摘要：White-box cryptography aims to give a secure soft- ware implementation of the cryptographic algo- rithm running in an untrusted environment which is owned and controlled by an adversary. Its major goal is to protect the confidentiality of the secret key. Given the increasing demands for software- only applications, white-box cryptography has re- ceived a lot of attention from industry. By now, all publications of white-box cryptographic(WBC) implementations from public literatures can be di- vided into two groups:(i) implementations of ex- isting block ciphers such as AES and DES;(ii) ded- icated designs of block ciphers which are assumed to run in the white-box environment.
