Final answer:
WEP uses a 24-bit initialization vector for encryption, combining it with a secret key. The limited IV size makes WEP susceptible to security issues.
Step-by-step explanation:
The size of the initialization vector (IV) that WEP (Wired Equivalent Privacy) uses for encryption is 24 bits. This IV is combined with a secret key to encrypt data. However, due to the limited size of the IV, WEP encryption can be vulnerable to certain types of attacks where the IVs can be reused, leading to security breaches.
The size of the initialization vector (IV) that WEP (Wired Equivalent Privacy) uses for encryption is 24 bit. The IV is a random number that is generated and used along with a secret key to encrypt data in wireless networks. In the case of WEP, the IV is concatenated with the secret key and passed through a stream cipher algorithm to generate the encryption key.
However, it is worth noting that WEP is no longer considered secure and is widely deprecated due to its vulnerabilities. Its use should be avoided, and more secure encryption protocols like WPA2 or WPA3 should be used instead.
