Secure Exp-Golomb coding using stream cipher

In this paper, we propose a secure Exp-Golomb coding scheme by incorporating with a stream cipher. Different from the traditional case of using stream cipher where the key stream is directly XORed with the plaintext, we here use the key stream to control the switching between two coding conventions (leading zeros and leading ones). Security analysis results show that the proposed system can provide high level of security with the same coding efficiency and negligible additional cost, compared with a regular Exp-Golomb coding. This scheme could potentially be applied to the state-of-the-art multimedia compression systems, e.g., H. 264, to offer security features.
