Abstract

Devices, systems, and methods for conducting trusted computing tasks on a distributed computer system are described. In some embodiments, a client device initiates a trusted task for execution within a trusted execution environment of a remote service provider. The devices, systems, and methods may permit the client to evaluate the trusted execution capabilities of the service provider via a planning and attestation process, prior to sending data/code associated with the trusted task to the service provider for execution. Execution of the trusted task may be performed while enforcing security and/or compartmentalization context on the data/code. Systems and methods for managing and exchanging encryption keys are also described. Such systems and methods may be used to maintain the security of the data/code before during, and/or after the execution of the trusted task.

First claim

What is claimed is:

1. A client device, comprising:
a processor;
communications circuitry; a memory; and
a client attestation module having computer readable trusted task initiation module (TTIM) instructions stored therein, wherein said TTIM instructions when executed by said processor cause said client device to perform the following operations comprising:
output a trusted task initiation signal (TTIS) with said communications circuitry to a plurality of service provider de…
