Abstract
Cloud computing grows as an important keyword to accelerate IT businesses. A feature of cloud
computing is distributed architecture based on unfixed nodes, and security risks have been high-
lighted for cloud computing services. In this paper, we present a novel approach for solving the
essential issue of cloud computing: how to protect a program running in an untrusted cloud comput-
ing environment. We apply a separation technique to the program and divide it into two pieces: a user
program and a protected program. Our security analysis shows that both internal and external attacks
require exponential computational costs; that is, our scheme is computationally secure against these
attacks.
