| | IEEE APPROVES TWO WIRELESS LAN PROJECTS THAT ADDRESS FAST ROAMING AND MESH STANDARDS |
 | | IEEE 802.11i was developed by the IEEE 802.11 Working Group, which is sponsored by the IEEE 802® LAN/MAN Standards Committee of the IEEE Computer Society. | | | "IEEE 802.11i was developed by leading experts in network security to give end users and network administrators a high level of assurance that the integrity of their networks and data will not be compromised," said Stuart J. Kerry, Chair of the IEEE 802.11 standards committee. | | | IEEE 802.11i, "Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications: Medium Access Control (MAC) Security Enhancement," leverages security technology that has emerged since the original IEEE 802.11 standard was written in the late 1990s. |

| | In July of 2001, IEEE 802.11i decided that it would not define EAP authentication types, voting that specific EAP authentication types are out of scope for the IEEE 802.11i specification except where it affects the IEEE 802.1X and/or IEEE 802.11 framework. | | | The following information is input from IEEE 802.11i regarding EAP. | | | IEEE 802.11i Draft 1.7, clause 8.1.4.2 requires authentication methods within 802.11 environments to perform mutual authentication and to establish keys based on the authentication. |

| | IEEE 802.11i Standard Improves Wireless LAN Security |
| | When the 802.11i task group began its work, there was no consensus that it was important to protect the control messages in a wireless network. | | | With 802.11i, the whole security chain for logging in, exchanging credentials, authenticating, and encryption becomes much more robust and effective in protecting against both nontargeted and targeted attacks, making it easier for people to both work and enjoy wireless entertainment anytime, anywhere. | | | IEEE 802 set up a committee, chaired by Intel, to study the ways in which WAPI could be integrated into 802.11. |

| | Since IEEE 802.1aa depends on RFC 2284bis, a reference to RFC 2284 in IEEE 802.11i could create confusion about the expected state machine behavior of the EAP implementation within IEEE 802.11i. | | | Dorothy noted that IEEE 802.11i depends on IEEE 802.1aa, which in turn depends on RFC 2284bis. | | | He also asked that IEEE 802.11i be specific about whether the purpose of the requirements was to serve as a set of requirements for selection of a single method (beauty contest for the mandatory-to-implement method) or just as requirements for any method that was to be used with IEEE 802.11i. |

| | The resulting IEEE 802.11i amendment has many components, the most obvious of which are the two new data-confidentiality protocols, TKIP and CCMP. | | | In the IEEE 802.11i specification, these exchanges are referred to as the 4-way handshake and the group key handshake. | | | The culmination of three and a half years of work by the IEEE 802.11i Task Group, the amendment adds stronger encryption, authentication, and key management strategies that go a long way toward guaranteeing data and system security. |

| | Since the IEEE 802.11 Task Group I security work had only just gotten underway at the time that the IEEE 802.1X standard was approved, 802.1X does not describe how the 802.1X and 802.11 state machines are to be coupled. | | | That task was left to IEEE 802.11 Task Group I. Since IEEE 802.1X is not a cipher, it is not an alternative to WEP, 3DES, AES, or any other cipher. | | | This means that IEEE 802.1X can scale from speeds of 11 Mbps (802.11) to 10+ Gbps, and can be enabled on existing switches with a firmware upgrade, without the need to buy new hardware. |

| | The IEEE's 802.11i project has been implemented, in part, by the Wi-Fi Alliance's Wi-Fi Protected Access (WPA) and by the Robust Secure Network (RNS). | | | The long-anticipated 802.11i specification for wireless LAN security was finally ratified by the IEEE in June 2004. | | | Another element of the 802.11i is Robust Security Network (RSN), which dynamically negotiates the authentication and encryption algorithms to be used for communications between WAPs and wireless clients. |

| | IEEE approves 802.11i security spec - infoSync World |
| | Adding to the alphabet soup that is the Wi-Fi family of protocols, the IEEE has approved a new wireless security protocol dubbed 802.11i, intended to finally provide sufficient security for wireless connections that users don't need to rely on alternate security layers. | | | 802.11i is expected to be certified as Wi-Fi Protected Access 2 (WPA2) compliant. | | | The IEEE has approved yet another specification in the 802.11 family of wireless ethernet. |

| | WPA2 is the Wi-Fi Alliance certification program, based on the support by equipment and software for what it considers to be mandatory features of 802.11i. | | | In addition, as VoIP/WLANs become more economically attractive and hardware vendors begin supporting the pre-authentication feature of 802.11i, it will see additional pull-through for its adoption. | | | The features in IEEE 802.11i and WPA2 are virtually identical. |
