With such specifications as the Wi-Fi Alliance's WPA 2 (Wi-Fi Protected Access 2 standard and the AES encryption algorithm from NIST (National Institute of Standards), wireless security is implementing, and wireless is set for deployment by the Department of Homeland Security (DHS). DHS now permits certified and accredited wireless network and has formed a wireless security working group to do risk assessments and to identify secure methods for deployment of wireless networks. WPA2 is a standard that includes AES encryption, and Ronald Jost, director of wireless at the Defense Department, has told attendees at conference that the department would be asking for WPA2 certified solutions when it procured wireless networks. That plan amounts to a strong endorsement, says a spokesman for the Wi-Fi Alliance. The Wi-Fi Alliance, a nonprofit industry group, was created to standardize the wireless network technologies for the 802.11 specification. The alliance includes such industry giants as IBM, Intel, AT&T, Cisco Systems, and Motorola. NIST guides standards implementation for information security via the Federal Information Processing Standards, especially FIPS 140-2, which describes how data must be encrypted to remain secure in a wireless network. The current WPA2 includes the Advanced Encryption Standard, which uses 128-bit keys to encrypt data and is a NIST standard. The wireless industry has also started adopting a method for AES use called counter mode and CBC-MAC (CCM), which meets the approval of NIST.
