Evaluation of the security against tamper resistance attacks on medical information network systems

Abstract

 Computer communication has been greatly expanded thanks to the Internet, enabling doctors at hospitals to exchange medical information to each other by e-mail. And Medical institutes of various fields can share their information by using the IC-cards with Electronic Medical Records in them. As the guide, we classify medical information systems into three types. In this paper, we point out the possible danger of relying too much on the tamper resistance alone in terms of security. Furthermore, we examine the necessity of security system using the cryptography technology via the network and examine the condition of security against various attacks.
