Core technology Edge Computing: Edge computing handles information processing, content collection and transmission, closer to IoT and machines, and supports computing on devices located at the edge of the network. Blockchain: Blockchain is a next-generation transactional application technology that sets the reliability, transparency, and accountability while streamlining complex processes. Authentication, Authorization, Accounting (AAA): Authentication verifies the user's identity before allowing access to the system. Authorization allows a level of authority and service to a verified user. Accounting collects usage information about users' resources and provides billing, auditing, capacity increase, and reporting.
- 6. 2. Related Works MFA is a method of user login authentication through two or more products or elements. Such authentication requires two or more authentication methods, including Fast Identity Online (FIDO) authentication. The MCA uses different independent channels such as web, mobile and IoT channels to transmit. The transmission procedure does not include personal information in the communications section.

Required design principles for multiple AAA system A secure and efficient network environment is need to solve current and future problems and meet new service requirements. Existing systems rely on evidence from a single source of information, such as fingerprint, face recognition, and iris recognition, required for existing authentication. Moreover, we have to solve various problems such as noise of detected data, similarity in class, and similarity. • Scalability: When designing an authentication system for future extended IoT networks, it is necessary to adapt to local conditions first. • Resilience: Multiple AAA systems using blockchain require various nodes. Blockchain nodes run continuously, and even if some nodes fail to compute, autonomous recovery is possible by providing improved resiliency through operations on subsequent nodes. • Security: Data between IoT networks and service providers is a design principle that security integrity and personal information are the most important.

For the safety of numerous data transmissions, the authentication process includes MFA and MCA, and discusses the application of various AAA systems on a blockchain basis. 3.1. Blockchain-based Multiple AAA System in Edge Computing for IoT Networks model Figure 1 depicts a multiple AAA system model as a whole in Edge computing, which is classified as a cloud layer, a fog layer, and a device layer. The cloud includes a variety of service models and can provide all sorts of apps that are included in the service. The fog layer consists of innumerable fog nodes, and the fog node is the core of the blockchain-based multiple AAA system. The blockchain guarantees safety and reliability by connecting the fog nodes together, and is efficient because there is no need for a trusted authority like the central cloud. The device layer represents a collection of various IoT devices.

The request and response is an IoT delivery device that updates the flow rule table of the blockchain network. Authentication and requests are formed into a blockchain-based multiple AAA system through the connection of such networks. Fig. 1.
