The Wi-Fi Alliance announced today the first set of companies whose products have received WPA2 certification: They include products from Atheros, Broadcom, Cisco, Instant802 Networks, Intel, and Realtek.
WPA2 is based on 802.11i and uses Advanced Encryption Standard instead of TKIP. Broadcom and Atheros are both touting their hardware-based solutions. Broadcom says that its existing products have shipped with the chip-based AES engine which means that simple software downloads can upgrade products to comply with WPA2.
Both Atheros and Broadcom products will be used by the Wi-Fi Alliance in certifying other WPA2 products.
