    Abstract: A key handshaking method in a WLAN is provided to enable a security key for authentication to be exchanged once through one 4-way handshake between an authenticator and a requester in the WLAN, thereby preventing delay of the authentication process between the authenticator station and the requester station in the WLAN. A key handshaking method in a WLAN(Wireless Local Area Network) comprises the following steps of: generating a first nonce at the first station(S104); transmitting the first nonce from the first station to the second station(S110); receiving the second nonce from the second station at the first station, and generating a PTK(Pair-wise Transient Key) based on the second nonce(S108); and installing the PTK in the first station(S118). In the above PTK generating step, a GTK(Group Transient Key) is generated together with the PTK if necessary.

    Abstract translation: 提供了WLAN中的关键握手方法，以便通过WLAN中的认证者和请求者之间的一次四次握手来使认证的安全密钥交换一次，从而防止认证者站和请求者之间的认证过程的延迟 站在WLAN。 WLAN（无线局域网）中的关键握手方法包括以下步骤：在第一站产生第一随机数（S104）; 将第一随机数从第一站传送到第二站（S110）; 在第一站处从第二站接收第二随机数，并且基于第二随机数生成PTK（成对瞬态密钥）（S108）; 并在第一站安装PTK（S118）。 在上述PTK生成步骤中，如果需要，与PTK一起生成GTK（组瞬态密钥）。
