A data access device for enforcing a data policy, including an input unit, a processing unit, a data exposure enforcement unit, and an output unit, where the data access device is configured to run in a trusted execution environment; the input unit is configured to receive a first data including a request for handling data, and a target identification; the processing unit is configured to process the first data to attain a second data including the target identification and a data structure according to requirements of an application running in the data access device; the data exposure enforcement unit is configured to manipulate the second data according to a data exposure policy to attain a third data; and the output unit is configured to output the third data.

Device and method for enforcing a data policy

In a method for software attestation, an enclave including an operating system (OS) library is initialized in a trusted execution environment, wherein software attestation is performed to verify an identity of the enclave, wherein an application is executed inside the enclave using the OS library, and wherein performing the software attestation includes attestation of a content of a disk image associated with the application.

Apparatus and method for disk attestation

A node provides a service to a client node in a network. The node is configured to execute a code for providing the service to the client node in an enclave of a trusted execution environment (TEE) and to execute a code library in the enclave to attest to the client node the identity of the service provided. The service provided to the client node may be a distributed service including a result of a cooperation of a plurality of neighbor nodes, which are connected to the node either directly or through other intermediate nodes. The code library is configured to attest to the client node the identity of the distributed service.
