Abstract
A method for generating a signed manifest includes referencing an object. A metadata name is recorded. A digest algorithm is recorded. An integrity value that belongs to the object that corresponds to the metadata subject name is digested with the digest algorithm.
Claims25
A method for generating a signed manifest, comprising:
- referencing an object;
- recording a metadata name;
- recording a digest algorithm;
- and
- digesting an integrity value that belongs to the object that corresponds to the metadata name with the digest algorithm.
A method for validating an integrity of an object, comprising:
- validating an integrity of a signed manifest corresponding to the object;
- and
- checking an integrity of the object with data in the signed manifest.
A computer-readable medium having stored thereon sequences of instructions, the sequences of instructions including instructions which, when executed by a processor, causes the processor to perform the steps of:
- referencing an object;
- recording a metadata name;
- recording a digest algorithm;
- and
- digesting an integrity value that belongs to the object that corresponds to the metadata name with the digest algorithm.
An object integrity verification unit, comprising:
- a signed manifest manager that records a metadata name and digest algorithm;
- and
- a digest unit, coupled to the signed manifest manager, that digests an integrity value corresponding to the metadata name with the digest algorithm.
A computer system, comprising:
- a bus;
- a processor coupled to the bus;
- and
- an object integrity verification unit, including a signed manifest manager that records a metadata name and digest algorithm, and a digest unit, coupled to the signed manifest manager, that digests an integrity value corresponding to the metadata name with the digest algorithm.
