Validating a high performance programmable secure coprocessor Indoor sax chat woman

This paper, a product of the seond phase of effort, records trend information developed primarily from in-house technical expertise.

This paper details our experiences with successfully validating a trusted device at FIPS 140-1 Level 4 - earning the world\‘s first certificate at this highest level.

In some sense, our validation effort was an experiment to quantify the design and work effort necessary to achieve this previously unachieved security assurance level.

, and at least one author has to have had an affiliation with the Watson team (although not necessarily when the paper was published).

We give a formal specification of the dynamic loading of classes in the Java Virtual Machine (JVM) and of the visibility of mmbers of the loaded classes.

This specification is obtained by abstracting out the part of the run-time state of the JVM that is relevant for dynamic loading and visibility, and consists of a set of inference rules defining abstract operations for loading, linking and verifying classes.

Successful validation at Level 4 required withstanding a fairly open-ended suite of physical attacks, and preparing formal modeling and verification of the internal software---as well as meeting a number of other sizable challenges that were not initially apparent. We chose FIPS 140-1, since discussions of secure hardware usually cite that standard, and Level 4, since the weaker levels did not provide sufficient assurance for many proposed applications.Successful validation at Level 4 required withstanding a fairly open-ended suite of physical attacks, and preparing formal modeling and verification of the internal software—as well as meeting a number of other sizable challenges that were not initially apparent.To learn more or modify/prevent the use of cookies, see our Cookie Policy and Privacy Policy.Abstract Secure coprocessors enable secure distributed applications by providing safe havens where an application program can execute (and accumulate state), free of observation and interference by an adversary with direct physical access to the device.
