  • Page 104

    NID names can also be used as a security measure, as described on page 101. NID name table The Nokia A032 can store a list of up to 200 NID names in its flash memory, in the NID name table.

  • Page 105: Using Nid Names

    Using NID names The basic approach to using NID names is as follows: Ascertain the MAC addresses of the cards to which you want to assign NID names. Assign the NID names, thereby updating the NID name table. If necessary, restrict network access to stations listed in the NID name table.

    However, if you don’t take steps to protect your network, unauthorized users could intercept data or even gain access to your network. The Nokia A032 provides comprehensive security measures to counter eavesdropping and to control access.

  • Page 134

    Eavesdropping is prevented by the use of encryption (data is scrambled such that only the sender and receiver can understand it). Authentication and encryption The Nokia A032 provides several levels of authentication and encryption. Choose the level that is appropriate for your environment: Level...

  • Page 135

    WEP depends on keeping the key away from unauthorized persons. The WEP encryption method is defined by IEEE802.11. This means that you can use the Nokia A032 in conjunction with other vendors’ wireless LAN clients that adhere to the standard.

  • Page 136: Wep Security Overview

    IEEE802.11 standard specifies 40-bit keys for general use. 40-bit keys provide a high degree of security uncrackable by all but the most determined attackers. The Nokia A032 allows the use of longer keys where local regulations permit, up to 128 bits in length.

  • Page 137

    Authentication Because secrecy of the key is paramount, WEP never transmits a key value over the network. The wireless client only needs to prove to the access point that it has a matching key. It achieves this using a method known as challenge-response: The wireless client indicates to the access point that it wants to connect.

  • Page 138: Key Management

    Even the most secure system is worthless if the secret keys are intercepted. Key management is a general term for the way in which you allocate and control key (password) allocation to users. The Nokia A032 provides two basic approaches for key management: •...

  • Page 139

    In this case all the wireless clients are loaded with the secret key information. The same key is loaded into the access point. The advantage of this approach is that it is simple to manage, since there is only one key active at a given time (chosen from an available ‘pool’...

  • Page 140

    Keys are stored on some other medium, such as a smart card which can be inserted into the wireless LAN adapter card. Nokia wireless LAN adapters support a range of these options. If you are required to enter a WEP key manually, you might be able to use an ASCII text string (e.g.

  • Page 141

    To assist in the management process Nokia provides a key management utility (WEPGen) with the Nokia A032 access point. This utility allows you to enter and modify lists of users and to store the lists (suitably encrypted) on a disk file.

    Setting WEP key policy At time of going to press, the IEEE802.11 standard specifies the use of 40-bit keys (five bytes). However, the Nokia A032 provides the option to use longer (i.e. stronger) keys if the network administrator chooses. Key lengths of 40, 56, 64, 96 and 128 bits are supported.

  • Page 145

    Note that the selected key length policy does not affect the size of the keys which can be entered and stored in the Nokia A032. Even if you have selected the use of 40-bit keys, it is possible to enter and store 128-bit keys (16 bytes) in the access point.

    In the Nokia A032 implementation, the sequence of events is as follows: The access point receives an authenticate request from a wireless client. The access point formulates a RADIUS request using the wireless client’s identifier (usually the MAC address) as the username and a fixed string (called the dummy password) for the password field.
