Abstract: Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In sonic embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key.

Abstract translation: 无线设备的实施例和无线网络中的具有减少的分组丢失的密钥的方法通常在本文中描述。 在一些实施例中，在重新键入操作期间，可以提前（即，在接收到密钥确认消息之前）安装用于接收的新密钥。 可以延迟使用新的密钥进行传输，直到接收到密钥确认消息为止。 早期安装接收的新密钥可以允许新密钥和旧密钥同时活动，以便使用解密接收到的数据包来减少密钥操作期间的数据包丢失。 密钥确认消息可以是用于密钥密钥的四次握手的第四消息。 在一些实施例中，两个键标识符可以在四次握手之间交替以防止删除旧密钥。
