Sample Application Demonstrations FIGURE 4-9: WPS AND SECURITY METHODS 4.5.7 Wireless Security 4.5.7.1 WIRED EQUIVALENT PRIVACY (WEP) Note: Several disadvantages are identified in WEP, which results in hackable and insecure networks. The use of WEP has been superceded by WPA/WPA2. WEP security has two forms: 64-bit WEP, which uses a 40-bit key (WEP-40) and 128bit WEP, which uses a 104-bit key (WEP-104). In the basic form, WEP keys have hexadecimal values, 5 bytes for WEP-40 and 13 bytes for WEP-104.
Microchip MRF24W Getting Started Guide for MRF24WB0MA/B, MRF24WG0MA/B for MLA v5 4.5.7.2 SETUP ACCESS POINT FOR WEP 1. Login to the router, see instructions in 2.5 “Wireless Access Point (AP) Setup”. 2. To access the wireless security options Wireless>Wireless Security, see Figure 4-10. FIGURE 4-10: 64-BIT WEP SECURITY SETUP 3. To match the default code in the hardware, choose security features as shown in Figure 4-11 (depending on whether 64-bit WEP or 128-bit WEP is used).
Sample Application Demonstrations 4.5.7.3 SETUP SOURCE CODE FOR WEP After the AP is configured for WEP, user must program the development board to use WEP. Configure the following for WEP, and it is located in WF_Config.h. For more information, see Figure 4-12. • Set the encryption type to WEP-40 or WEP-104. Define MY_DEFAULT_WIFI_SECURITY_MODE to either WF_SECURITY_WEP_40 or WF_SECURITY_WEP_104 • Set the WEP phrase. Refer to MY_DEFAULT_WEP_KEYS_40 or MY_DEFAULT_WEP_KEYS_104.
Microchip MRF24W Getting Started Guide for MRF24WB0MA/B, MRF24WG0MA/B for MLA v5 4.5.8.1 TO SET UP AP FOR WPA/WPA2 PERSONAL 1. Login to the router, refer instructions in the 2.5 “Wireless Access Point (AP) Setup”. 2. Access the wireless security options by Wireless>Wireless Security. For WPA Personal, see Figure 4-13. For WPA2 Personal, use WPA algorithm (AES) only see Figure 4-14. 3. To match the default code in the hardware, set up the security as shown in Figure 4-13 and Figure 4-14.
Sample Application Demonstrations 4.5.9 Setup Source Code for WPA/WPA2 The MRF24WB0MA/B or MRF24WG0MA/B Wi-Fi® PICtail™ has the following two approaches to run WPA/WPA2 security: • On-the-fly PSK Calculation - The straight forward approach to supply the passphrase. The PIC18/24/32 or PICtail will calculate the PSK based on the SSID and the supplied passphrase. Due to the computationally intensive nature of this operation, this will take approximately 30 seconds to 45 seconds to complete.
Microchip MRF24W Getting Started Guide for MRF24WB0MA/B, MRF24WG0MA/B for MLA v5 4.5.9.2 PRE GENERATED PSK Users can pre generate the PSK and use 32 byte PSK in the source code. The handy tool to generate the PSK is available online at the Wireshark Foundation (see Appendix A.4). The Wireshark web site can generate the expected 32 byte PSK key with the SSID name and the passphrase. Use these values in the variable MY_DEFAULT_PSK in WF_Config.h. For more information, see Figure 4-16.
