eapol 4 way handshake
對網路安全而言，key愈少傳輸愈好，因此4-way handshake用來建立512 bits的PTK(Pairwise Transient Key)。 ... 128 bits的EAPOL-Key Confirmation Key (KCK)，用來計算WPA EAPOL key message的MIC. 2. 128 bits的EAPOL-Key Encryption Key (KEK)，用來加密額外要送給STA的的data，如GTK or RSN IE. 3., KRACK的漏洞中有三個跟EAPOL 4-way handshake有關，分別是CVE-2017-13077、CVE-2017-13078及CVE-2017-13079，EAPOL 4-way handshake的過程發生在802.1x的認證後或者使用PSK的AP及STA之間，或者說只要是802.1x或者是使用WPA2 PSK的環境無一倖免，EAPOL 4-way handshake的過程主要 ..., 随后AP与STA通过EAPOL-KEY进行WPA的四次握手（4-Way Handshake）过程，如图所示。 在这个过程中，AP和STA均确认了对方是否持有与自己一致的PMK，如不一致，四次握手过程就告失败。为了保证传输的完整性，在握手过程中使用了名为MIC（Message Integrity Code）的检验码。在四次握手的过程中，AP ...,, 4-Way handshake utilizing EAPOL-Key frames initiated by the Authenticator to do the following. 1. Confirm that live peer holds PMK 2. Confirm that PMK is current. 3. Derive a fresh PTK from PMK & Install the pairwise encryption & integrity keys i, EAPOL stands for Extensible Authentication Protocol(EAP) over LAN. A simple 4-way handshake is shown pictorially below. A top level description of a successful 4-Way-Handshake is explained below. At the start of the 4-way handshake, both the Access Point,IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to e, 攻擊WPA2-Personal. 對WPA2-Personal 最有效的攻擊方式是抓取到一開始的EAPoL 封包，關鍵的是前面的幾個封包，我們稱其為4-Way Handshake 封包，就是一開始STA 與AP 之間的Nounce 交換過程，透過開源碼工具aircrack-ng 使用字典檔方式來破解，詳見本站文章。, The installation of Pairwise and Groupwise Transient Keys (PTK/GTK) is done by the so called 4-Way Handshake with the following flow graph: ... KU Leuven, Belgium) published his research paper on how the EAPoL key exchange can be attacked to read encrypt,Marcus Burton, Director of Product Development at CWNP, teaches you the 802.11 4-way handshake.
