What do wap encrypted tkip and EAS mean in wireless wifi? What is the difference?

Tkip and EAS encrypted by wap in wireless wifi are two different encryption protocols and standards. TKIP is a kind of "temporal key integrity protocol" that can dynamically change the key, and AES is an advanced encryption standard. The differences are as follows:

1, different specifications:

In IEEE? In the 802. 1 1i specification, TKIP: temporal key integrity protocol is responsible for the encryption of wireless security issues. Advanced Encryption Standard (AES) in cryptography, also known as Rijndael encryption method, is a block encryption standard adopted by the federal government of the United States.

2. The key length is different:

The key length used in TKIP password is 128 bits. The block length of AES is fixed at 128 bits, and the key length can be 128, 192 or 256 bits.

Extended data:

TKIP and WPA standards realize three new security functions:

1, TKIP realizes the key mixing function, and passes the combination of secret and root key initialization vectors to RC4 before initialization. Instead, WEP is just an RC4 routine that connects to the root key initialization vector and passes the value.

2.WPA implements a sequence counter to prevent replay attacks. In order to receive packets, the access point will be denied.

3.TKIP implements 64-bit message integrity check (MIC).

TKIP related functions:

TKIP is a layer of "shell" that wraps the existing WEP password. TKIP consists of the same encryption engine and RC4 algorithm used by WEP. However, the key length used in TKIP password is 128 bits. This solves a problem of WEP: the key length is too short.
