Chapter 4 (continued) Encryption type WEP encryption AES TKIP Description Benefits Limitations Devices on a network share a password, called a "WEP key" to encode and decode data. Simplest strategy that provides encryption. All devices must have the key. The WEP key does not change automatically. WEP encryption provides less security than both AES or TKIP. Advanced Encryption Standard (AES) is a U.S. government sponsored encryption method that uses a complex algorithm called "Rijndael." AES uses encryption keys to encode data. AES automatically changes the encryption keys after a certain time interval, thus making the wireless network less vulnerable to eavesdropping. Since the encryption key changes automatically, the data is more difficult for eavesdroppers to decode. All devices must have the key. Temporal Key Integrity Protocol (TKIP) uses encryption keys to encode data. TKIP automatically changes the encryption keys after a certain time interval, thus making the wireless network less vulnerable to eavesdropping. Since the encryption key changes automatically, the data is more difficult for eavesdroppers to decode. All devices must have the key. 30 HP Deskjet 6980 series
