White box cryptographic algorithms aim to denying the key readout even if the source code embedding the key is disclosed. Full-privileged attack software shares a host with cryptographic software, having complete access to the implementation of algorithms, dynamic execution (with instantiated cryptographic keys) can be observed and internal algorithm details are completely visible and alterable. Chow proposed a new technique to secure cryptographic algorithms and key against white-box attacks, called white-box cryptography. Another technique such as obfuscation is mainly designed to facilitate securing of e-commerce and e-banking applications, which often embed cryptographic keys and critical information.
