still have sufficient password strength to prevent it from being easily decrypted. Another disadvantage of WEP is "replay attacks". Each packet transmitted using TKIP has a unique 48-bit serial number, because the 48-bit serial number takes thousands of years to repeat, no one can replay the old data packets from wireless connections: Because the serial number is incorrect, these data packets will be detected as out-of-order packets.

With these features, the disadvantages of WEP that were previously criticized have to be completely solved. WPA includes temporary Key Integrity Protocol (Temporal Key Integrity Proto)Col, TKIP) and 802.1x. Together with 802.1x, TKIP provides dynamic key encryption and mutual authentication functio

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After five years of selection process, the Advanced Encryption Standard was issued by the National Institute of Standards and Technology (NIST)
