User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U Ad Hoc Mode (Peer-to-Peer Workgroup) In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network—each node can generally communicate with any other node. There is no access point involved in this configuration.

User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U WEP Wireless Security The absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless computer can join any network and receive any messages that are not encrypted.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U • Shared Key Authentication requires that the station and the access point have the same WEP Key to authenticate. These two authentication procedures are described below. WEP Open System Authentication This process is illustrated below. 802.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U WEP Shared Key Authentication This process is illustrated below. 802.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U Key Size and Configuration The IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit. The 64-bit WEP data encryption method, allows for a five-character (40-bit) input. Additionally, 24 factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 factory-set bits are not user-configurable).
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U How to Use WEP Parameters Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode. There are two shared key methods implemented in most commercially available products, 64-bit and 128-bit WEP data encryption. Before enabling WEP on an 802.11 network, you must first consider what type of encryption you require and the key size you want to use.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U • • • • Enhanced data privacy Robust key management Data origin authentication Data integrity protection Starting in August of 2003, all new Wi-Fi certified products had to support WPA and all existing Wi-Fi certified products had one year to comply with the new standard or lose their Wi-Fi certification. NETGEAR has implemented WPA on client and access point products. As of August 2004, all Wi-Fi certified products must support WPA.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U How Does WPA Compare to IEEE 802.11i? WPA is forward compatible with the IEEE 802.11i security specification currently under development. WPA is a subset of the current 802.11i draft and uses certain pieces of the 802.11i draft that were ready to bring to market in 2003, such as 802.1x and TKIP. The main pieces of the 802.11i draft that are not included in WPA are secure IBSS (Ad-Hoc mode), secure fast handoff (for specialized 802.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured passphrase on both the stations and the access point. This removes the need for an authentication server, which in many home and small office environments will not be available nor desirable.

User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U 3. The client sends an EAP-response packet containing the identity to the authentication server. The access point responds by enabling a port for passing only EAP packets from the client to an authentication server located on the wired side of the access point. The access point blocks all other traffic, such as HTTP, DHCP, and POP3 packets, until the access point can verify the client's identity using an authentication server (e.g.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U 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.
User’s Manual for the NETGEAR Super AG Wireless USB 2.0 Adapter WG111U Is WPA Perfect? WPA is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS) attacks.
