In the vertical multi-level public network, the ciphertext video needs to support the distribution of key in the whole network when it is shared across different security domains horizontally. However, the traditional key management mode faces great pressure on the security classification and encryption efficiency, and especially, it cannot fully ensure the security of content and key when sharing across-domains. Based on the above analysis, this paper proposes a cross domain video security sharing solution based on white box encryption theory to improve the security of video data sharing. In this solution, the white box encryption technology is adopted to establish the data sharing background trust mechanism based on the key management center, and we study the white box key protection technology of the video terminal to support the mass level key distribution in the network and the online security generation and replacement of the white box password module, so that the safe and fast cross domain exchange and sharing of video data are realized.
