In 2002, the researcher introduced the concept of white-box cryptography by presenting a white-box implementation of AES. White-box cryptography aims to protect the confidentiality of the secret key of a cipher in a white-box environment. In a white-box environment, an adversary is assumed to have full access to the implementation of the cipher and its execution environment. For example, in a white-box environment the adversary can use tools such as decompilers and debuggers to reverse engineer the implementation of the cipher, and to read and alter values of intermediate results of the cipher during its execution.
