EAP-AKA-Prime
What is the Expansion of EAP-AKA-Prime?
EAP-AKA-Prime stands for Extensible Authentication Protocol - Authentication and Key Agreement (AKA) Prime.
It is an enhanced version of EAP-AKA, designed for authentication and key management in mobile networks, specifically 5G and 4G LTE.
What is EAP-AKA-Prime?
EAP-AKA-Prime is an authentication protocol used for secure communication between mobile devices (like smartphones) and network servers.
It is an evolved version of EAP-AKA, primarily used in 5G networks for authentication and key agreement between devices and the network.
It provides stronger protection against certain types of attacks compared to its predecessor (EAP-AKA).
Why is EAP-AKA-Prime useful?
Improved Security: EAP-AKA-Prime is more resistant to security threats, such as man-in-the-middle attacks and credential theft, offering enhanced protection for mobile network communications.
Enhanced Authentication: It uses a more secure process for mutual authentication, which ensures that both the client and the network are verified.
Supports 5G Networks: EAP-AKA-Prime is built for next-generation mobile networks, making it essential for 5G technology.
How it works?
Key Exchange: The device and network exchange cryptographic keys using EAP-AKA-Prime to secure communications and ensure that unauthorized devices cannot connect.
Mutual Authentication: Both the device and the network authenticate each other, ensuring trust and secure data transfer.
Session Key Generation: After authentication, a session key is generated, which is used to encrypt communication between the device and the network.
Where is EAP-AKA-Prime used?
Mobile Networks: It is used extensively in 4G LTE and 5G mobile networks for authentication and secure key management.
SIM-based Authentication: Used in scenarios where a SIM card is present in mobile devices, especially for cellular and Wi-Fi networks.
Which OSI layer does this protocol belong to?
EAP-AKA-Prime operates at the Application Layer (Layer 7) of the OSI model.
It is part of the EAP framework and relies on lower layers for transport (such as RADIUS).
Is EAP-AKA-Prime Windows specific?
No, EAP-AKA-Prime is not Windows-specific.
It can be used on any platform that supports the EAP framework, including Android, iOS, Linux, and Windows.
Is EAP-AKA-Prime Linux Specific?
No, EAP-AKA-Prime is not Linux-specific.
It can work across multiple operating systems, as long as the network supports the EAP-AKA-Prime protocol, which is designed to be OS-agnostic.
Which Transport Protocol is used by EAP-AKA-Prime?
EAP-AKA-Prime uses the RADIUS protocol for communication between the client (mobile device) and the server (authentication server).
RADIUS typically uses UDP (User Datagram Protocol) as the transport protocol.
Which Port is used by EAP-AKA-Prime?
EAP-AKA-Prime operates over UDP port 1812 for authentication requests, which is the default port for RADIUS.
Is EAP-AKA-Prime using Client-server model?
Yes, EAP-AKA-Prime follows the client-server model.
The client (e.g., mobile device) authenticates with the server (e.g., network authentication server), and the server makes decisions based on the client’s credentials.
Whether EAP-AKA-Prime protocol uses certificates?
Yes, EAP-AKA-Prime can utilize certificates in certain cases to verify the authenticity of the server or the client during the authentication process.
These certificates help in securing the authentication process and preventing man-in-the-middle attacks.
How many frame exchanges are seen during connection for EAP-AKA-Prime protocol?
- The EAP-AKA-Prime connection procedure typically involves three frame exchanges:
Initial Authentication Request
Authentication Response
Authentication Success/Failure
Whether EAP-AKA-Prime Protocol uses client certificates?
No, EAP-AKA-Prime generally does not require client certificates.
It relies on SIM-based authentication and other methods for verifying the client’s identity.
Whether EAP-AKA-Prime Protocol uses Server Certificates?
Yes, EAP-AKA-Prime typically uses server certificates to verify the authenticity of the network (server) during the authentication process.
Is EAP-AKA-Prime Protocol depends on TCP?
No, EAP-AKA-Prime typically depends on UDP, since it uses the RADIUS protocol for transport, which operates over UDP.
Is EAP-AKA-Prime Protocol depends on UDP?
Yes, EAP-AKA-Prime relies on UDP for transport, since it uses RADIUS over UDP for authentication and other communication.
What are the roles involved when testing EAP-AKA-Prime Protocol?
Testers/Engineers: Individuals responsible for validating the functionality and security of the protocol.
RADIUS Server: The server that handles authentication requests.
Client Devices: Mobile devices, such as smartphones, which are involved in the connection process.
Does EAP-AKA-Prime Protocol work with free radius server on Linux?
Yes, EAP-AKA-Prime can work with the FreeRADIUS server on Linux.
FreeRADIUS supports various EAP protocols, including EAP-AKA-Prime, for authentication purposes.
Does EAP-AKA-Prime Protocol work with Internal radius server of hostapd?
Yes, EAP-AKA-Prime can work with the internal RADIUS server provided by hostapd on Linux systems.
Hostapd supports various EAP methods, including EAP-AKA-Prime.
What is the RFC version used for EAP-AKA-Prime Protocol?
The RFC version for EAP-AKA-Prime is RFC 4187.
It is part of the broader EAP framework for authentication.
During Connection Procedure which EPoL Packets are encrypted?
During the connection procedure, the EAP-AKA-Prime protocol encrypts the authentication and key exchange packets to ensure privacy and prevent tampering.
Can you Explain different stages of Connection Procedure for EAP-AKA-Prime Protocol?
Stage 1: The mobile device sends an EAP-Request/Identity packet.
Stage 2: The server responds with an EAP-Response/Identity packet and performs authentication.
Stage 3: The key exchange process is completed, followed by the EAP-Success message.
What is the final output of Connection Procedure?
The final output is the generation of a session key (PMK), which is used to establish a secure connection between the client device and the network.
What is the format of the key generated after the connection procedure?
The key generated is typically a PMK (Pairwise Master Key) used for encrypting data traffic during the session.
Where is the use of PMK generated by the Connection Procedure?
The PMK is used to generate the PTK (Pairwise Transient Key) during the connection process, ensuring encrypted communication between the mobile device and the network.
