The paper studies the protection of memory privacy under virtual platform to enhance system security. Based on the monitoring of foreign mapping for Dom0, a memory privacy protection scheme is designed and implemented to prevent process memory pages in DomU being mapped illegally which might result in the leakage of secret data.展开更多
