EAP-TLS

What is Expansion of EAP-TLS?

EAP-TLS stands for Extensible Authentication Protocol - Transport Layer Security.

What is EAP-TLS?

EAP-TLS is an authentication protocol that uses Transport Layer Security (TLS) to provide strong mutual authentication between a client and a server using digital certificates.

Why is EAP-TLS useful?

  • Provides strong security through mutual authentication.

  • Uses digital certificates to eliminate the need for passwords.

  • Widely supported and standardized.

  • Protects against man-in-the-middle attacks and replay attacks.

How it works?

  • Client and server exchange certificates during the TLS handshake.

  • Both verify each other’s certificates.

  • A secure TLS tunnel is established.

  • Session keys are generated for further encrypted communication.

Where is EAP-TLS used?

  • Enterprise Wi-Fi networks (WPA-Enterprise).

  • VPN authentication.

  • Any environment requiring strong certificate-based authentication.

Which OSI layer does this protocol belong to?

  • Application Layer (Layer 7) of the OSI model.

  • Operates within the EAP framework transported over network layers.

IS EAP-TLS windows specific?

  • No, it is platform-independent.

  • Supported on Windows through native supplicants and third-party software.

IS EAP-TLS Linux Specific?

  • No, it’s supported widely on Linux via wpa_supplicant and other tools.

Which Transport Protocol is used by EAP-TLS?

  • Runs over EAP, which is commonly encapsulated over: * EAPOL (Ethernet) * RADIUS (UDP) * Diameter (TCP/SCTP)

Which Port is used by EAP-TLS?

  • RADIUS authentication: UDP port 1812

  • Diameter (if used): TCP port 3868

Is EAP-TLS using Client server model?

  • Yes.

  • Client (supplicant) and Authentication Server (e.g., RADIUS).

Whether EAP-TLS protocol uses certificates?

  • Yes, both client and server use X.509 certificates for mutual authentication.

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

  • Approximately 10–12 EAP message exchanges depending on TLS handshake details.

Whether EAP-TLS Protocol uses client certificates?

  • Yes, client certificates are mandatory for authentication.

Whether EAP-TLS Protocol uses Server Certificates?

  • Yes, server certificates are mandatory.

IS EAP-TLS Protocol depends on TCP?

  • Indirectly, if Diameter backend is used.

  • EAP itself is transport agnostic.

IS EAP-TLS Protocol depends on UDP?

  • Yes, typically when using RADIUS backend (UDP).

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

  • Supplicant (client)

  • Authenticator (e.g., AP)

  • Authentication Server (e.g., FreeRADIUS)

  • Certificate Authority (CA)

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

  • Yes, FreeRADIUS has robust EAP-TLS support.

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

  • No, hostapd’s internal radius server does not support EAP-TLS.

What is the RFC version use for EAP-TLS Protocol?

  • RFC 5216

During Connection Procedure which EPoL Packets are encrypted?

  • EAPOL packets themselves are not encrypted.

  • After key derivation, subsequent data packets are encrypted.

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

  • Client initiates EAP identity.

  • Server requests TLS handshake.

  • Client and server exchange certificates.

  • TLS session is established and keys are generated.

  • Server sends EAP Success.

  • Session keys (MSK) are handed over to authenticator for encryption.

What is the final output of Connection Procedure?

  • Generation of Master Session Key (MSK) and Extended MSK (EMSK).

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

  • MSK: 64 bytes (512 bits)

  • EMSK: 64 bytes (512 bits)

Where the use of PMK generated by the Connection Procedure?

  • PMK (Pairwise Master Key) is derived from MSK and used in 4-way handshake for encrypting wireless data.

# 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
