Wind River® Wireless Ethernet Driver provides access point and station-side support for the industry-standard 802.11a, b, and g protocols. Designed to work with any wireless chipset, the driver comes standard with direct support for Atheros AR500x wireless chipsets. A fully abstracted hardware interface layer provides ease of portability to other wireless chips.
Wireless Ethernet Driver directly supports any PCI card that uses the Atheros AR500x chipset, and it supports multiple hardware interfaces on the same target, allowing more advanced applications. The driver can be used in a wide variety of target hardware platforms, and a standard IOCTL application interface is provided for user configuration and control. Wireless security is provided through pre-integration with the Wind River Wireless Security protocol suite, supporting the 802.1X, WPA, and 802.11i standards.
Wind River Wireless Security
Wind River Wireless Security is a suite of security protocols employed in a wide range of wireless devices. The suite includes both supplicant and authenticator for the 802.1X, Wi-Fi Protected Access (WPA), and 802.11i protocols.
For VxWorks®, the Wireless Security authenticator is integrated with Wind River RADIUS Client, Wind River Learning Bridge, and Wireless Ethernet Driver, providing all the core functionality for typical authenticator products, such as wireless access points. Although integrated and validated with Wireless Ethernet Driver, the Wireless Security implementation can be used with any wireless chipset with an appropriate driver that includes WPA/802.11i low-level support.
Both supplicant and authenticator can be used in the same product, providing greater flexibility and a wide range of application support. Extensible Authentication Protocol (EAP) types are supported. The security implementation includes pre-shared keys, Temporal Key Integrity Protocol (TKIP), and Michael Countermeasures. A range of encryption and hashing algorithms are available to give developers flexibility in trading off security level versus performance. Integration with Wind River SNMP is included to interface with the 802.1X MIB.
Wind River WPASUP (Wireless Supplicant)
Available for Wind River Linux, WPASUP handles all 802.1x messages and interfaces with Wind River Network Stack and a wireless driver. It runs in Linux user space. It is integrated with WPA and WPA2 and works with several EAP methods, as mandated by the Wi-Fi Alliance.
