US 2015/0101033 A1 · RETRIEVAL OF DATA ACROSS MULTIPLE PARTITIONS OF A STORAGE DEVICE USING DIGITAL SIGNATURES

Abstract

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.

Dependent claims

A method for data retrieval across multiple partitions, the method comprising:

receiving, from a first application, a request for data stored in a first partition of a storage device, wherein the first application is included in a second partition of the storage device and wherein the first partition of the storage device includes a second application;
in response to receiving the request, comparing a signature of a global certificate that is associated with each of the first application and the second application;
based on the comparison indicating that the signature from each of the first application and the second application match, using a key from the certificate associated with the first application to identify the data from a data store included in the first partition;
and
transmitting the data from the data store included in the first partition to the first application.

2 more elements

A system for data retrieval across multiple partitions, the system comprising:

a hardware processor;
a storage device coupled to the hardware processor, the storage device including a first partition, a second partition, and instructions that, when executed by the hardware processor, cause the processor to:
receive, from a first application, a request for data stored in a first partition of a storage device, wherein the first application is included in a second partition of the storage device and wherein the first partition of the storage device includes a second application;
in response to receiving the request, compare a signature of a global certificate that is associated with each of the first application and the second application;
based on the comparison indicating that the signature from each of the first application and the second application match, use a key from the certificate associated with the first application to identify the data from a data store included in the first partition;
and
transmit the data from the data store included in the first partition to the first application.

4 more elements

A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a hardware processor, cause the process to perform a method for data retrieval across multiple partitions, the method comprising:

receiving, from a first application, a request for data stored in a first partition of a storage device, wherein the first application is included in a second partition of the storage device and wherein the first partition of the storage device includes a second application;
in response to receiving the request, comparing a signature of a global certificate that is associated with each of the first application and the second application;
based on the comparison indicating that the signature from each of the first application and the second application match, using a key from the certificate associated with the first application to identify the data from a data store included in the first partition;
and
transmitting the data from the data store included in the first partition to the first application.
