Abstract
A module-specific public key and cryptographically protected data related to the module-specific public key are extracted from an authenticable and verifiable module. The cryptographically protected data is compared with the module-specific public key to authenticate the authenticable and verifiable module. A value calculated from an image, including a size and location block, included within the authenticable and verifiable module is compared with a value extracted from a digital signature contained in a verification block within the authenticable and verifiable module to verify the authenticable and verifiable module.
