Abstract

A method of ensuring the integrity of read-only components in deployed mixed-mode applications that includes generating a digital fingerprint prior to the deployment of a mixed-mode application is discussed. The digital fingerprint is based on a read-only component in the mixed-mode application and uniquely identifies the read-only component. The method also deploys the mixed-mode application and the digital fingerprint. Additionally, the method verifies, at execution time by using the digital fingerprint, that the read-only component in the mixed-mode deployed application that served as the basis for the digital fingerprint is identical to the same read-only component originally packaged with the mixed-mode application.

First claim

I claim:

1. A method comprising:
receiving a request to execute an application in an execution environment,
the application being associated with an authorization file that is uniquely identified,
the receiving the request to execute the application being performed by a device,
the application comprising a read-only component and pseudo-code,
the read-only component comprising source code, and
the pseudo-code being executable by a virtual machine;

determining, based…
