US 2021/0281431 A1 · NVDIMM SECURITY WITH PHYSICALLY UNCLONABLE FUNCTIONS

Abstract

Authenticating a host computer and NVDIMM pair using lookup tables for a challenge/response exchange between the pair of devices. The NVDIMM is challenged by the host computer for which a response associated with the physically unclonable function of a NVDIMM component is provided. The NVDIMM challenges the host computer for which a response associated with the physically unclonable function of a host computer component is provided. Additional security stores a modified response associated with run-time physically unclonable functions associated with the host computer and NVDIMM pair for use in future challenge/response exchanges.

Dependent claims

A computer-implemented method for authenticating a host/NVDIMM pair, the method comprising:

transmitting a first challenge to a non-volatile dual in-line memory module (NVDIMM) installed in a host computer;
receiving, from the NVDIMM, a first response to the first challenge, the first response including a second challenge;
generating, by the host computer, a second response to the second challenge;
sending the second response and a first acknowledgement of the first response to the NVDIMM;
receiving, from the NVDIMM, a second acknowledgement of the second response;
and
authenticating the host computer and the NVDIMM as a recognized host/NVDIMM pair based on the first and second acknowledgements.

4 more elements

A computer program product for authenticating a host/NVDIMM pair, the method comprising:

a set of storage device(s);
and
computer code stored collectively in the set of storage device(s), with the computer code including data and instructions to cause a processor(s) set to perform at least the following operations:
transmitting a first challenge to a non-volatile dual in-line memory module (NVDIMM) installed in a host computer,
receiving, from the NVDIMM, a first response to the first challenge, the first response including a second challenge,
generating, by the host computer, a second response to the second challenge,
sending the second response and a first acknowledgement of the first response to the NVDIMM,
receiving, from the NVDIMM, a second acknowledgement of the second response, and
authenticating the host computer and the NVDIMM as a recognized host/NVDIMM pair based on the first and second acknowledgements.
