Novel file system with ASN.1 support for Java Card applications

摘要

By the release of Java Card 3.0 Connected version and the rapid evolution of ubiquitous computing, many embedded software applications have been proposed recently to exploit the benefits of the new technology. These recent research and software development activities make it inevitable to defend the new applications in the open untrusted environments through proposing parallel research in securing embedded software platforms. This paper proposes a novel File System Applet for existing Java Card systems that provides highly secure storage for security-critical objects of the other residing Applets. The new file system Applet depends on PKCS15 and ISO7816 standards and features new built-in ASN.1 parser to prevent intended/unintended leakage of sensitive information.
