Abstract

In some embodiments, a system includes a signature server comprising a signature unit to receive an update to a software application. The signature server also includes a first machine-readable medium to store a mapping between an identification of the software application and an address of a location of a private key. The system includes a cryptographic device coupled to an external port of the signature server. The cryptographic device includes a second machine-readable medium to store the private key. The cryptographic device also includes a cryptographic unit to generate a signature of the update based on the private key.

First claim

What is claimed is:

1. A computer-implemented method comprising:
downloading manifest data for a software update into a client device, the manifest data including a manifest data signature, a software update storage location, and a software update signature;
verifying the manifest data by generating a first hash across the manifest data using an updateable public key stored in a file directory of the client device and comparing the first hash to the manifest data signature;
do…
