EAP-GPSK

What is Expansion of EAP-GPSK?

EAP-GPSK stands for Extensible Authentication Protocol - Group Pre-Shared Key.

What is EAP-GPSK?

EAP-GPSK is an authentication protocol that provides secure access to wireless networks using a Group Pre-Shared Key (GPSK). It eliminates the need for individual certificates and instead uses a shared key for authentication, offering a simpler and more efficient alternative to traditional certificate-based EAP methods.

Why is EAP-GPSK useful?

Simplified Authentication: EAP-GPSK eliminates the need for complex certificates, making it easier to manage and implement.
Faster Connection: It allows faster authentication compared to certificate-based methods.
Scalable: Ideal for environments with multiple devices, like enterprise wireless networks, where setting up certificates for each device might be inefficient.
Secure: Uses a shared key and encryption to ensure secure communication between the client and server.

How it works?

Client and Server: The client and server both have a Group Pre-Shared Key (GPSK) for authentication.
Authentication: The client initiates authentication by proving its knowledge of the GPSK without sending the actual key. The server validates the key and grants access if successful.
Secure Tunnel: A secure tunnel is established to protect the data exchange between the client and server during the authentication process.

Where is EAP-GPSK used?

Enterprise Wi-Fi: EAP-GPSK is commonly used in wireless networks where simplicity, speed, and security are necessary.
Public Wi-Fi: It can be used in environments such as cafes or public hotspots where ease of setup is a priority.

Which OSI layer does this protocol belong to?

EAP-GPSK operates at the Application Layer (Layer 7) of the OSI model, interacting with lower layers for data transport through protocols like RADIUS.

IS EAP-GPSK Windows specific?

No, EAP-GPSK is not Windows-specific.
It is supported across various platforms, including Windows, Linux, macOS, and mobile operating systems.

IS EAP-GPSK Linux Specific?

No, EAP-GPSK is not Linux-specific.
It is available on multiple platforms and can be used in both Linux and Windows environments.

Which Transport Protocol is used by EAP-GPSK?

EAP-GPSK uses RADIUS as its transport protocol, which typically relies on UDP for communication.

Which Port is used by EAP-GPSK?

EAP-GPSK typically uses UDP port 1812 for authentication and UDP port 1813 for accounting, as it relies on RADIUS.

Is EAP-GPSK using Client server model?

Yes, EAP-GPSK follows a client-server model.
The client initiates the authentication process, while the server (usually a RADIUS server) authenticates the client and grants access.

Whether EAP-GPSK protocol uses certificates?

No, EAP-GPSK does not use certificates.
It uses a Group Pre-Shared Key (GPSK) instead of certificates for authentication.

How many frame exchanges are seen during connection for EAP-GPSK protocol?

EAP-GPSK typically involves two or three frame exchanges for authentication:
- One for establishing the secure tunnel.
- Another for key exchange and successful authentication.

Whether EAP-GPSK Protocol uses client certificates?

No, EAP-GPSK does not use client certificates.
Authentication is based on a shared Group Pre-Shared Key (GPSK).

Whether EAP-GPSK Protocol uses Server Certificates?

No, EAP-GPSK does not use server certificates.
Instead, it uses the Group Pre-Shared Key (GPSK) for authentication.

IS EAP-GPSK Protocol depends on TCP?

No, EAP-GPSK relies on UDP for transport, not TCP.

IS EAP-GPSK Protocol depends on UDP?

Yes, EAP-GPSK depends on UDP as the transport protocol, typically using RADIUS over UDP.

What are the roles involved when testing EAP-GPSK Protocol?

Client: Initiates the authentication request and provides the GPSK.
RADIUS Server: Processes the request, verifies the GPSK, and authenticates the client.
Administrator: Configures the RADIUS server, ensures GPSK management, and tests the network setup.

Does EAP-GPSK Protocol work with free radius server on Linux?

Yes, EAP-GPSK works with FreeRADIUS on Linux.
It can be configured to use the GPSK for authentication with FreeRADIUS servers.

Does EAP-GPSK Protocol work with Internal radius server of hostapd?

Yes, EAP-GPSK can be used with the internal RADIUS server of hostapd for wireless network authentication.

What is the RFC version used for EAP-GPSK Protocol?

The RFC version for EAP-GPSK is RFC 5931.

During Connection Procedure which EPoL Packets are encrypted?

During the authentication process, EAP-GPSK packets are encrypted to ensure the confidentiality of the shared key and other sensitive information.

Can you Explain different stages of Connection Procedure for EAP-GPSK Protocol?

Stage 1: The client sends an authentication request.
Stage 2: The server responds, and a secure channel is established.
Stage 3: Key exchange and client verification take place.
Stage 4: The client is authenticated, and network access is granted.

What is the final output of Connection Procedure?

The final output is a successful authentication, where the client is granted access to the network based on the shared Group Pre-Shared Key (GPSK).

What is the format of the key generate after the connection procedure?

After the connection procedure, a Pairwise Master Key (PMK) is generated, which is used for securing the data channel between the client and the server.

Where the use of PMK generated by the Connection Procedure?

The PMK is used for securing the wireless connection between the client and the server.
It is used in the generation of encryption keys for the data exchange during the established connection.

# hostapd depends on strong random number generation being available from the
# operating system. os_get_random() function is used to fetch random data when
# needed, e.g., for key generation. On Linux and BSD systems, this works by
# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
# properly initialized before hostapd is started. This is important especially
# on embedded devices that do not have a hardware random number generator and
# may by default start up with minimal entropy available for random number
# generation.
#
# As a safety net, hostapd is by default trying to internally collect
# additional entropy for generating random data to mix in with the data
# fetched from the OS. This by itself is not considered to be very strong, but
# it may help in cases where the system pool is not initialized properly.
# However, it is very strongly recommended that the system pool is initialized
# with enough entropy either by using hardware assisted random number
# generator or by storing state over device reboots.
#
# hostapd can be configured to maintain its own entropy store over restarts to
# enhance random number generation. This is not perfect, but it is much more
# secure than using the same sequence of random numbers after every reboot.
# This can be enabled with -e<entropy file> command line option. The specified
# file needs to be readable and writable by hostapd.
#
# If the os_get_random() is known to provide strong random data (e.g., on
# Linux/BSD, the board in question is known to have reliable source of random
# data from /dev/urandom), the internal hostapd random pool can be disabled.
# This will save some in binary size and CPU use. However, this should only be
# considered for builds that are known to be used on devices that meet the

# wpa_supplicant depends on strong random number generation being available
# from the operating system. os_get_random() function is used to fetch random
# data when needed, e.g., for key generation. On Linux and BSD systems, this
# works by reading /dev/urandom. It should be noted that the OS entropy pool
# needs to be properly initialized before wpa_supplicant is started. This is
# important especially on embedded devices that do not have a hardware random
# number generator and may by default start up with minimal entropy available
# for random number generation.
#
# As a safety net, wpa_supplicant is by default trying to internally collect
# additional entropy for generating random data to mix in with the data fetched
# from the OS. This by itself is not considered to be very strong, but it may
# help in cases where the system pool is not initialized properly. However, it
# is very strongly recommended that the system pool is initialized with enough
# entropy either by using hardware assisted random number generator or by
# storing state over device reboots.
#
# wpa_supplicant can be configured to maintain its own entropy store over
# restarts to enhance random number generation. This is not perfect, but it is
# much more secure than using the same sequence of random numbers after every
# reboot. This can be enabled with -e<entropy file> command line option. The
# specified file needs to be readable and writable by wpa_supplicant.
#
# If the os_get_random() is known to provide strong random data (e.g., on
# Linux/BSD, the board in question is known to have reliable source of random
# data from /dev/urandom), the internal wpa_supplicant random pool can be
# disabled. This will save some in binary size and CPU use. However, this
