Digital trust broker and end to end trust assurance in multi-domain, multi-operator and cloud networks for high security environments
System and methods of brokering trust across multiple Authentication and Authorization methods in a multi-domain, multi-operator, private and public cloud networks are identified. A Digital Trust Broker (DTB) is disclosed that brokers trust between infrastructure authentication methods that use digital certificates (PKI) and operator/enterprise Authentication/Authorization methods through interaction with multiple operator/service provider control and management platforms. The Digital Trust Broker interacts with vendor management and security platforms for associating device manufacturing, assembly, supply-chain, and logistics attributes for assuring trust of compute, network, storage and other system components that a high security enterprise or service provider acquires and installs in their networks. Additionally, methods of generating enhanced certificates for secure network slices and other Cloud and SDN hosted virtual network functions as trust assured services are also disclosed.
1. A method of allowing an enterprise to create a Secure Network Slice, which is a multi-point secure network having a plurality of endpoints, within a multi-domain multi-provider network, comprising:
determining a plurality of access networks at each endpoint;
interacting with an Orchestration and Management Platform (OMP) within each of the plurality of access networks to determine entry and exit points for each access network;
identifying transit networks and cloud or Software Defined Network (SDN) providers to be traversed to connect to the endpoints;
using an OMP interface to ensure that each network device within each transit network and cloud or SDN providers comprises a set of required attributes;
creating a set of trusted network segments and network equipment through the transit networks and cloud or SDN providers; and
negotiating with the transit networks and cloud or SDN providers to create a Secure Network Slice.
2. The method of claim 1 , wherein the set of trusted network segments and network equipment attributes is provided to an operator of one of the access networks and the operator negotiates with the transit networks and cloud or SDN providers.
3. The method of claim 1 , wherein the enterprise negotiates with the transit networks and cloud or SDN providers.
4. The method of claim 1 , further comprising periodically revalidating the Secure Network Slice.
5. The method of claim 1 , wherein the required attributes are selected from the group consisting of function, vendor name, hardware model number, hardware version number, manufacturer Name, manufacturer Location, Region, Operating System vendor, Version number, Geo location, and device capabilities and features.
6. The method of claim 5 , wherein the device capabilities and features are selected from the group consisting of packet filters, deep packet inspection and content-aware processing controls, mirroring, and packet flooding controls.
7. The method of claim 1 , wherein the required attributes are stored in an enhanced digital certificate (eDC).
8. A method of allowing an enterprise to create a trusted network in multiple security environments managed by enterprises, operator and service providers, wherein the network comprises a Secure Network Slice (SNS) and a second network that utilizes different authentication and authorization methods, comprising:
using a digital trust broker (DTB), which comprises one or more software applications;
creating a DTB client application that communicates with the DTB;
allowing a trusted device in the second network to authenticate devices in the second network using methods specific to the second network; and
using the DTB to bridge trust between the SNS and the second network.
9. The method of claim 8 , wherein the methods specific to the second network are selected from the group consisting of IOT, EAP, CHAP, MFA, RADIUS, 802.1X, QR Codes, Bluetooth, and mobile wireless network protocols.
10. The method of claim 8 , wherein the second network comprises an IoT network comprising an IOT gateway and a plurality of IOT devices; and wherein the IOT gateway authenticates the IOT devices using a method specific to IOT protocols.
11. The method of claim 10 , wherein the IOT devices and the IOT gateway communicate using a wireless network or wired network.
12. The method of claim 11 , wherein the wireless network comprises Bluetooth, WIFI, NFC, or 5G.
13. The method of claim 8 , wherein the second network comprises a mobile wireless network comprising a User Data Management (UDM), a plurality of mobile devices and mobile applications, wherein the UDM authenticates the mobile devices using a method specific to 5G.
14. The method of claim 13 , wherein the mobile applications comprise applications that interact with the DTB for security and trust validation for connecting to the SNS.
