Abstract
Disclosed is a system and method that uses digital signature technology to authenticate the contents of one or more manifests located on a storage device. Each manifest contains a list of file records, where each record contains the name of a file stored on the storage device, and a signature value derived from the contents of the file. At boot time, the gaming machine first authenticates the contents of the manifest and then authenticates the contents of the files using the signature value stored in the manifest. Files are verified using the signature, as they are needed, during the boot up of the operating system and throughout normal operation. This method reduces the boot time of the gaming machine and eliminates the need to check digital signatures for each individual file or over the entire contents of a non-secure media.Similarly, a method of adding authentication ability to legacy software components without necessarily altering the legacy software components is disclosed. Introduction of a stronger authentication algorithm, or when a private key has been compromised would normally require the software component to be re-built to support the new algorithm or private/public …
