WebWEP Encryption Two processes are applied to the plaintext data. One encrypts the plaintext; the other protects the data from being modified by unauthorized personnel. The 40-bit secret key is connected with a 24-bit Initialization Vector (IV) resulting in a 64-bit total key size. WebAll 40-bit and 56-bit encryption algorithms are obsolete, because they are vulnerable to brute force attacks, and therefore cannot be regarded as secure. [6] [7] As a result, virtually all Web browsers now use 128-bit keys, which are considered strong.

WebTKIP uses a similar key structure to WEP with the low 16-bit value of a sequence counter (used to prevent replay attacks) being expanded into the 24-bit "IV", and this sequence counter always increment on every new packet. An attacker can use this key structure to improve existing attacks on RC4. WebMar 6, 2024 · Because WEP uses 24-bit IVs, which is quite small, IVs ended up being re-used with the same key.
