Retrieval of Data Across Multiple Partitions of a Storage Device Using Digital Signatures

摘要

A system and method for exchanging data among partitions of a storage device is disclosed. For example, data stored in a first partition is exchanged with an application included in the first partition or with a second application included in a second partition. In one embodiment, the second application is associated with a global certificate while the first application is associated with a different platform certificate. A verification module included in the first partition receives a request for data and determines if the request for data is received from the first application. If the request for data is not received from the first application, the verification module determines whether the request is received from the second application and whether the global certificate is an authorized certificate. For example, the verification module determines whether the global certificate is included in a listing of authorized certificates.
