Abstract

White-box cryptography is a software obfuscation technique for cryptography implementation. It can protect the secret key even if an attacker has full access and control over the cryptosystem implementation and its execution platform. There have been several proposals for a white-box implementation of cryptography. We propose a white-box implementation of a stream cipher that can achieve the same asymptotic performance as the standard implementation. Our black-box implementation of KCipher-2 achieves low storage consumption of no more than 2 megabytes and is suitable for a PC, tablet, and smartphone. On the other hand, we can achieve space hard implementation to protect against a code-lifting attack. Furthermore, the implementation can protect against black-box attacks and a BGE attack.
