A Watermark-Aware Trusted Running Environment for Software Clouds

A software cloud is ready-made for software delivery or Software as a Service (SaaS). As it becomes more and more popular, security problems of software running in the cloud also become an important issue. The threats, such as destroying system softwares and access violation, are frequently emerging in the field of software cloud. In this paper, we propose a watermark-aware trusted running environment to protect the softwares running in the cloud. We implement the scheme which mainly contains two parts: 1) embedding watermark into the Java programs running in the cloud; 2) generating customized JVMs for recognizing the watermarked programs. Experimental results within a real private software cloud to demonstrate that our approach can provide a large-scale protection with a small overhead.
