IEEE 802.1X is a standard for port-based network access control, typically used to provide secure authentication on both wired (Ethernet) and wireless networks. Here's a breakdown of the key components and implementation steps for 802.1X over Ethernet:

1. Supplicant (Client)
   • The device (e.g., a computer or network printer) that requests access to the network.
   • It must support 802.1X and be configured with credentials (such as a username/password or certificate) to authenticate to the network.
2. Authenticator (Switch or Access Point)
   • The network device that acts as an intermediary between the supplicant and the authentication server.

• In the case of Ethernet, this is typically an Ethernet switch. The switch only allows network access if the supplicant is successfully authenticated.

802.1x is a network access control protocol that provides authentication for devices trying to connect to a LAN or WLAN. It’s commonly used in enterprise environments to secure Ethernet and Wi-Fi networks. The authentication is usually performed using RADIUS servers.

• Check Device Compatibility:
  • Not all Android devices natively support Ethernet connections, and support for 802.1x over Ethernet can be even rarer. First, ensure your device supports Ethernet connections either through a USB-to-Ethernet adapter or a built-in Ethernet port.
• Connect the Ethernet Adapter:
• If your device doesn’t have a built-in Ethernet port, you’ll need a USB-to-Ethernet adapter. Once connected, your device should recognize the Ethernet connection automatically.

OTA is the mechanism by which OEMs remotely update the system partition of a device:

• Android 5.0 and later versions use block OTA updates to ensure that each device uses the exact same partition. Instead of comparing individual files and computing binary patches, block OTA handles the entire partition as one file and computes a single binary patch, ensuring the resultant partition contains exactly the intended bits. This allows the device system image to achieve the same state via fastboot or OTA.
• Android 4.4 and earlier versions used file OTA updates, which ensured devices contained similar file contents, permissions, and modes, but allowed metadata such as timestamps and the layout of the underlying storage to vary between devices based on the update method.

File based OTA update in not available beyond AOSP Android 5.0. Sometimes it is require to provide few configuration files along with OTA.

We have solution that provide file based OTA supports along with block-based OTA file. This solut

"As of now Android doesn’t support 802.1x Authentication over Ethernet natively."

Below components need to be changed/modified

• Ethernet Supplicant
• Ethernet Supplicant interface
• EthernetManager and EthernetService
• IPConfiguration

Proposed solution supports EAP-TLS, EAP-PEAP, EAP-TTLS, EAP-MD5 and EAP-PWD authentication methods.

Download the OpenSSH source code and replace it with existing source code inside external folder.

Add below code in device make file (e.g. device.mk).
