Abstract
Provided are servers and methods for authenticating software files. A server includes a processor circuit and a memory coupled to the processor circuit. The memory includes computer program instructions that, when executed by the processor circuit, cause the authentication server to perform operations including verifying, using a public key, signature data corresponding to a single certificate file for authenticating a software installation package file that was signed using a private source key. Operations may include, responsive to verifying that the signature data matches an originally signed single certificate file, reading an image file segment table from the software installation package file. The image file segment table includes multiple records that correspond to ones of multiple image file segments of the software installation package file.
