Description
Digital signatures enable the system to verify the integrity of the signed object and authenticate the object's signatory. Failure to maintain the binding of digital signatures on software components and applications in storage makes it more likely that an adversary could modify or replace those objects. Conversely, the bindings enable the operating system to verify the software's integrity and source with a high degree of assurance whenever necessary.
