- the present invention relates to computer systems, and more particularly to a system and method for ensuring the integrity of components employed by application programs at runtime.
- DLLs dynamically linked libraries
- Other files that are shared by different application programs.
- DLLs are listed within tables in application components to be linked at runtime.
- An operating system will search in a loader search path, application directory, operating system directory or user specified path for the name of the dynamic linked library, so that DLL code can be loaded into memory for execution. Since these DLLs can be shared by different application programs, changes to a DLL for one application may cause another application to stop operating.
- Microsoft Windows Operating System platform is the inability to control an exact set of dynamic link libraries and other files that will run as part of a deployed application program. It is quite common to have installation of one application program affect other application programs by overwriting files that those applications depend on.
- the present invention relates to a system and method of providing security and facilitating the integrity of components or assemblies ⁇ e.g., components including metadata), employed during runtime by application programs.
- the present invention employs cryptographic techniques to facilitate relationship between components. Administrators and developers can utilize this system and method to facilitate that an exact set of dynamic link libraries (DLLs) and other files that have been tested together can in fact run together after they are deployed. Assemblies carry version information that can be used to enforce the versioning rules described by the application program. At runtime, version numbers requested by the application programs are compared with those version numbers of the assemblies that are actually found. In addition to comparing version numbers, the present invention offers a stricter form of version checking based on cryptographic hashes.
