Abstract: Provided are system and method for establishing a topology for advertising supplicants a network. According to embodiments, the system may include: a memory storage storing computer-executable instructions; and at least one processor communicatively coupled to the memory storage, wherein the at least one processor may be configured to execute the instructions to: create a first authentication list for a first network entity, wherein the first authentication list specify one or more network entities that are authenticated with the first network entity; and advertise the first authentication list to a second agent deployed in a second network entity, wherein the second network entity is authenticated with the first network entity.

Abstract: Provided are features for determining authentication status information of an Open Radio Access Network (O-RAN) Radio Unit (O-RU). According to embodiments, an O-RU controller may be configured to: obtain a Media Access Control (MAC) address of an O-RU; determine, based on the MAC address of the O-RU, an authentication status of the O-RU; based on determining that the O-RU has been authenticated, establish a channel binding with the O-RU; and based on determining that the O-RU has not been authenticated, isolate the O-RU from further communications with the O-RU controller.

Abstract: Provided are system, method, and device for enabling network entities to view authenticated supplicants in a network. According to embodiments, the system may include: a memory storage storing computer-executable instructions; and at least one processor communicatively coupled to the memory storage, wherein the at least one processor may be configured to execute the instructions to: create a first authentication list for a first network entity; receive a second authentication list from a second network entity; and create a trust list for the first network entity based on the first authentication list and the second authentication list, wherein the trust list for the first network entity specifies a trust level between the first network entity and one or more network entities in the first and second authentication lists.
