This mixed WPA2 TKIP+AES mode is sometimes called PSK2-mixed mode.
To set your router to use only WPA2, choose WPA2 with AES (do not use TKIP). This option allows users to easily transition from WPA to WPA2. The passphrase for both WPA and WPA2 will be the same. When your router is set to " WPA2 with TKIP+AES" it means that network devices that can use WPA2 will connect with WPA2, and network devices that can only use WPA will connect with WPA. In essence: WPA = WPA with TKIP = PSK WPA2 = WPA with AES = PSK2 When you set your router to use WPA2, you usually have the option to use AES, or TKIP+AES. Many different strategies and protocols are used to secure LAN and WAN. CCMP uses 128-bit AES encryption with a 48-bit initialization vector.
Recall that counter mode (CM) is one of the modes in which block ciphers can operate. Lets try to break down CCMP into its individual parts to simplify and explain it. Under the hood of CCMP is the AES algorithm. WPA uses a Temporal Key Integrity Protocol ( TKIP ), which scrambles encryption keys using a hashing algorithm. CCMP provides authentication, confidentiality, and integrity checking services to any cryptographic system in which it is used. WPA uses TKIP encryption, WPA2 uses AES, but can also use TKIP for backward-compatability (so it would accept WPA connections). What is the strength of CCMP in terms of bits Answers 1. The algorithm for WPA2 is public, and tools like hashcat generate candidates, hash them, and compare them to the original hash - at speed. WPA and WPA2 encryption standards can sometimes be confusing.
