DEVICE ENROLLMENT SERVICE SYSTEM AND METHOD
Endpoints, such as Session Initial Protocol enabled telephones, are capable of being public network (e.g., Internet) devices and, as such, require security measures to protect the endpoints and components on a private network they may be attached to, such as a call center. By providing a self-signed certificate into an endpoint with hardcoded certificate authorities (CAs) that enable the phone to call a trusted location, namely a Device Enrollment Service (DES) having a verifiable record of the endpoint that, on endpoint startup, authentication actions may be performed and, is successful, the endpoint is permitted to “point to” other services that may allow the endpoint to be redirected or otherwise use a particular private network, such as that of a customer.
1 . A system, comprising:
a network interface;
a data storage comprising a non-volatile portion;
a processor; and
wherein, the processor, upon determining a first attachment to a network:
accesses a first address within the data storage;
attempt mutual authentication with a first service provided at the first address;
upon successfully performing mutual authentication with the first service, receiving from the first service a certificate a second address and a signed certificate; and
reconfiguring the system to communicate with a second service at the second address.
2 . The system of claim 1 , wherein the processor further provides the second service with the signed certificate to be authenticated by the second service.
3 . The system of claim 1 , wherein the processor, upon receiving a request to generate a self-signed certificate, generates a self-signed certificate and a hash of the self-signed certificate and provides the hash to the first service.
4 . The system of claim 3 , wherein the system provides the hash to the first service via providing the hash to a manufacture of the system for forwarding to the first service.
5 . The system of claim 1 , wherein the self-signed certificate comprises the first address.
6 . The system of claim 1 , wherein the processor, following successfully mutual authentication, establishes a secure channel with the first service to receive the signed certificate.
7 . A system, comprising:
a data storage;
a processor;
a network interface; and
wherein the processor:
receives, via the network interface, a request for mutual authentication from an endpoint;
in response to the received request, performs mutual authentication with the endpoint;
upon successfully performing the mutual authentication, providing the endpoint with a certificate to enable the endpoint to utilize a network.
8 . The system of claim 7 , further comprising generating the certificate signed by the system utilizing a public key of the system.
9 . The system of claim 7 , wherein processor receives a unique identifier of the endpoint from a manufacture of the endpoint.
10 . The system of claim 7 wherein the unique identifier is a Media Access Control (MAC) address.
11 . The system of claim 7 wherein the processor receives a hash of the certificate from a manufacture of the endpoint.
12 . The system of claim 11 , wherein the processor utilizes the hash of the certificate to perform the mutual authentication.
13 . The system of claim 7 , wherein the data storage maintains a record identifying a service provider with a customer.
14 . The system of claim 13 , wherein the record is updated upon receiving, from the service provider, a request to associate a third party with the service provider.
15 . The system of claim 14 , wherein the request further identifies a customer.
16 . The system of claim 14 , further comprising:
receiving a request to from a reseller to update a record that associate an endpoint with a service provider for a customer; and
upon determining that the data storage maintains a record granting permission for the update, performing the update.
17 . A system, comprising:
a data storage;
a processor;
a network interface; and
wherein the processor:
receives, via the network, a certificate from an endpoint;
upon receiving the certificate, validates the certificate utilizing a public key maintained in the data storage; and
upon successfully validating the certificate, adding the endpoint to a list of trusted endpoints to thereby enable the endpoint to utilize a network.
18 . The system of claim 17 , wherein the network is a network of a client utilizing the endpoint.
19 . The system of claim 17 , wherein the certificate is provided by a manufacture of the endpoint.
20 . The system of claim 17 , wherein the processor further receives, via the network, notification from a reseller that an endpoint is to be assigned to a customer and, in response thereto, the system notifies a device enrollment service (DES) to update a profile stored therein such that when the DES is queried the endpoint is known and known to be associated with the customer.
