Using Public Key Certificates to Ensure Subsystem Component Level Compatibility This disclosure describes a methodology in which a subsystem (or group of related programs) may ensure its components are at a compatible level to one another by using Public Key Signatures. This methodology creates a signature of the programs at compile time and allows the subsystem to verify itself during runtime. With computer applications becoming increasingly complex, they are being split into interdependent components in order to simplify the development and support processes. This split makes the process of ensuring each component on a computer system is at a compatible level more complex. Without this verification, an application may fail to function as designed.
