临时密钥完整性协议（英文：Temporal Key Integrity Protocol，缩写：TKIP）是一种用于IEEE 802.11无线网络标准中的替代性安全协议，由电气电子工程师学会（IEEE）802.11i任务组和Wi-Fi联盟设计，用以在不需要升级硬件的基础上替代有线等效加密（WEP）协议。由于WEP协议的薄弱造成了数据链路层安全被完全跳过，且由于已经应用的大量按照WEP要求制造的网络硬件急需更新更可靠的安全协议，在此背景下临时密钥完整性协议应运而生。需要注意的是，临时密钥完整性协议自2012年的802.11标准中，已不再视为完全，且即将废弃。

Temporal Key Integrity Protocol or TKIP /tiːˈkɪp/ was a stopgap security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware. This was necessary because the breaking of WEP had left WiFi networks without viable link-layer security, and a solution was required for already deployed hardware. TKIP is no longer considered secure and was deprecated in the 2012 revision of the 802.11 standard.
