Abstract

A network interface device comprises a first area of trust comprising a first part of the network interface device, the first part comprising one or more first kernels. A second area of trust comprising a second part of the network interface device different to said first part is provided, the second part comprising one or more second kernels. A communication link is provided between the first area of trust and the second area of trust. At least one of the first and second areas of trust is provided with isolation circuitry configured to control which data which is passed to the other of the first and second areas via the communication link.

Dependent claims

A network interface card (NIC) comprising:

a first area of trust comprising a first part of the NIC, wherein a first kernel is in the first area of trust and the first area of trust is associated with a first address space;
a second area of trust comprising a second part of the NIC different to the first part, wherein a second kernel is in the second area of trust and the second area of trust is associated with a second address space, separate from the first address space;
and
a communication link between the first area of trust and the second area of trust,
wherein the first area of trust is provided with isolation circuitry associated with the first kernel and configured to control which data is passed to the second area of trust via the communication link.
