Abstract
A distributed processing system includes one or more accelerated units (AUs) connected to a network. To control access to the AUs by one or more users over the network, the distributed processing system includes a control plane circuitry connected to the network. The control plane circuitry is configured to grant a user access to one or more AUs connected to the network based on user security data stored at the control plane circuitry. The security data stored at the control plane circuitry indicates which resources of one or more AUs connected to the network one or more users are authorized to access.
Claims20
A distributed processing system, comprising:
- an accelerated unit (AU) connected to a network;
- and
- control plane circuitry connected to the network and configured to:
- generate an encrypted user access set identifying one or more hardware resources of the AU a user is authorized to access based on user security data indicating one or more users authorized to access the AU;
- and
- wherein the AU is configured to, in response to receiving the encrypted user access set, allow the user access to one or more hardware resources of the AU based on the encrypted user access set.
An accelerated unit (AU), comprising:
- one or more processor cores;
- and
- trusted execution environment (TEE) circuitry connected to a network and configured to:
- receive, over the network, an encrypted user access set associated with a user requesting access to the AU, wherein the encrypted user access set indicates one or more hardware resources of the AU the user is allowed to access and wherein the encrypted user access set is encrypted by control plan circuitry connected to the network;
- and
- in response to receiving the encrypted user access set, allow the user to access the one or more hardware resources of the AU based on a signature of the encrypted user access set.
A method, comprising:
- receiving, at an AU connected to a network, an encrypted user access set associated with a user requesting access to the AU, wherein the encrypted user access set identifies one or more hardware resources of the AU the user is allowed to access and wherein the encrypted user access set is encrypted at control plane circuitry connected to the network;
- and
- in response to receiving the encrypted user access set, allowing, by the AU, the user to access the one or more hardware resources of the AU based on a signature of the encrypted user access set.
