Framework for ensuring software components are not corrupted

A method for validating of a container file for use by a medical device support application configured for use in conjunction with a medical device, the container file including a container header and a plurality of assets suitable for use by the medical device support application, each asset including an asset header and asset data, the method comprising:

• hashing at least a portion of the container file using a first hashing protocol to create a first hash value, wherein the hashed portion of the container file includes at least all of the assets;
• comparing the first hash value to a container file hash stored in the container header to determine whether the first hash value matches the container file hash, wherein when the first hash value and the container file hash do not match, the container file is treated as not valid;
• for each asset included in the container file, (i) hashing at least a portion of the asset using a second hashing protocol to create an asset validation hash value, wherein the hashed portion of the asset includes at least the asset data associated with the asset, and (ii) comparing the received asset validation hash value to an original asset hash value stored in the asset header associated with the asset to determine whether the asset validation hash value matches the original asset hash value, wherein when the asset validation hash value and the original asset hash value do not match, the container file is treated as not valid;
• and
• wherein the container file is only validated when at least the first hash value matches the container file hash value and each asset validation hash value matches the associated original asset hash value.

A method of creating a container file suitable for use by a medical device support application, the method comprising:

• for each of a plurality of assets that include an asset header and an asset body, hashing at least the body portion of the asset to create an asset hash and inserting the asset hash into an asset hash field in the asset header;
• inserting each of the assets into a container file, the container file including a container header;
• hashing at least a portion of container file including at least all of the assets to create a container hash;
• inserting the container hash into a container hash field in the container file.
