SYSTEMS AND METHODS FOR HARDWARE SECURITY MODULE AS CERTIFICATE AUTHORITY FOR NETWORK-ENABLED DEVICES

摘要

A new approach is proposed that contemplates systems and methods to support a trusted local certificate authority (CA) running on a hardware security module (HSM), wherein the trusted local CA is configured to issue a certificate to each of a plurality of network-enabled devices for authentication. The HSM further includes a plurality of HSM service units each configured to process key management and crypto operations offloaded from each of the network-enabled devices once it is authenticated. Each of the network-enabled devices is configured to accept its certificate for authentication from the trusted local CA, establish a secured communication channel with the HSM over a network and present the certificate to the HSM in a request for authentication, and offload its key management and crypto operations to one of the HSM service units once the network-enabled device is authenticated.

1. A system, comprising:
a hardware security module (HSM) comprising
a trusted local certificate authority (CA) running on the HSM, wherein the trusted local CA is configured to issue a certificate to each of a plurality of network-enabled devices for authentication;a plurality of HSM service units running on the HSM, wherein each of the HSM service units is configured to process key management and crypto operations offloaded from the network-enabled device once it is authenticated; said plurality of network-enabled devices each configured to
accept its certificate for authentication from the trusted local CA;establish a secured communication channel with the HSM over a network and present the certificate to the HSM in a request for authentication;offload its key management and crypto operations to one of the HSM service units over the secured communication channel once the network-enabled device is authenticated.
