Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3

Temporal Key Integrity Protocol (TKIP)

WPA uses TKIP to provide important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the following:

•The verification of the security configuration after the encryption keys are determined.

•The synchronized changing of the unicast encryption key for each frame.

•The determination of a unique starting unicast encryption key for each preshared key authentication.

Michael

With 802.11 and WEP, data integrity is provided by a 32-bit integrity check value (ICV) that is appended to the 802.11 payload and encrypted with WEP. Although the ICV is encrypted, you can use cryptanalysis to change bits in the encrypted payload and update the encrypted ICV without being detected by the receiver.

With WPA, a method known as Michael specifies a new algorithm that calculates an 8-byte message integrity check (MIC) using the calculation facilities available on existing wireless devices. The MIC is placed between the data portion of the IEEE 802.11 frame and the 4-byte ICV. The MIC field is encrypted together with the frame data and the ICV.

Michael also provides replay protection. A new frame counter in the IEEE 802.11 frame is used to prevent replay attacks.

AES Support for WPA2

One of the encryption methods supported by WPA2 is the advanced encryption standard (AES), although AES support will not be required initially for Wi-Fi certification. This is viewed as the optimal choice for security conscience organizations, but the problem with AES is that it requires a fundamental redesign of the NIC’s hardware in both the station and the access point. TKIP is a pragmatic compromise that allows organizations to deploy better security while AES capable equipment is being designed, manufactured, and incrementally deployed.

WG602v3 specifications

The NETGEAR WG602v3 is a wireless access point designed primarily for home and small office environments. As part of the NETGEAR family of networking devices, the WG602v3 ensures reliable and secure wireless connectivity, making it an essential component for users who require a seamless internet experience.

One of the main features of the NETGEAR WG602v3 is its support for the IEEE 802.11g wireless standard, which allows for data transfer rates of up to 54 Mbps. This standard ensures compatibility with older 802.11b devices while providing enhanced performance for newer wireless devices. The WG602v3 operates in the 2.4 GHz frequency band, ensuring widespread coverage and the ability to penetrate walls and barriers, making it suitable for diverse environments.

Another significant characteristic of this access point is its user-friendly setup process. The WG602v3 includes an intuitive web-based user interface that allows users to configure settings with ease. This simplifies the installation process and enables users, even those with limited technical knowledge, to quickly establish a robust wireless network.

Security is paramount in today’s interconnected world, and NETGEAR has incorporated several security features into the WG602v3. The device supports Wi-Fi Protected Access (WPA and WPA2) encryption protocols, ensuring that users can secure their data and prevent unauthorized access. Additionally, the WG602v3 includes a MAC address filtering feature that further enhances network security by allowing only designated devices to connect to the network.

The WG602v3 is also equipped with a detachable antenna, allowing users to customize their wireless coverage based on their specific needs. This adaptability makes it easier to optimize the access point’s performance in different physical layouts. Furthermore, it supports Power over Ethernet (PoE), enabling installation in locations without an accessible power outlet, which is particularly useful in unconventional setups.

In summary, the NETGEAR WG602v3 wireless access point combines ease of use, robust security features, and flexibility in installation to provide reliable connectivity. Its compatibility with both 802.11g and b devices, combined with user-friendly configuration options, ensures that it meets the needs of various users, from casual home users to small office setups, making it a versatile solution for enhancing wireless networks.
