WEP VS WPA PSK TKIP PASSWORD
WEP VS WPA PSK TKIP OFFLINE

To enable WPA3-incapable STAs to access a WPA3-configured network, the Wi-Fi Alliance defines the WPA3 transition mode. WPA3-Enterprise supports Suite B, which uses 192-bit minimum-strength security and supports Galois Counter Mode Protocol-256 (GCMP-256), Galois Message Authentication Code-256 (GMAC-256), and SHA-384. The CNSA Suite has a powerful encryption algorithm and applies to scenarios with extremely high security requirements. However, WPA3 enhances the algorithm strength by replacing the original cryptography suite with the Commercial National Security Algorithm (CNSA) Suite defined by the Federal Security Service (FSS). WPA3-Enterprise still uses the authentication system of WPA2-Enterprise and uses the Extensible Authentication Protocol (EAP) for identity authentication.

WEP VS WPA PSK TKIP PASSWORD

Even if an attacker knows the password on the network, the attacker cannot decrypt the obtained traffic, greatly improving the security of a WPA3-Personal network. In addition, the SAE handshake protocol provides forward secrecy.

WEP VS WPA PSK TKIP OFFLINE

Compared with WPA/WPA2-PSK authentication, WPA3-SAE can effectively defend against offline dictionary attacks and mitigate brute force cracking posed by weak passwords. WPA3-Personal introduces the SAE handshake protocol. GCM is short for Galois/Counter Mode.īased on application scenarios and security requirements, there are two WPA3 modes: WPA3-Enterprise and WPA3-Personal, that is, WPA3-802.1X and WPA3-SAE. That is, WPA3 supports AES-GCM with a 256-bit key and 384-bit curve elliptic curve encryption.

The algorithm strength is enhanced and support Suite B cryptography.

Therefore, the use of SAE makes WPA3 much more secure than earlier WPA standards. That is, an attacker can decrypt obtained traffic using the password. A WPA2 network, however, is vulnerable to password cracking attacks. Even if an attacker knows the password on a network, the attacker cannot decrypt the obtained traffic. Theoretically, SAE provides forward secrecy.

WPA3 introduces Simultaneous Authentication of Equals (SAE), which is a more secure handshake protocol.

If the encryption mode is TKIP-AES, any STAs supporting TKIP or AES can encrypt service packets.Ĭompared with WPA and WPA2, WPA3 has the following improvements: If the security policy is WPA-WPA2, STAs supporting WPA or WPA2 can be authenticated. To enable various types of STAs to access the network and facilitate management by network administrators, configure both WPA and WPA2. STAs vary and support different authentication and encryption modes. If STAs support only WEP encryption, 802.1X+TKIP can be implemented without a hardware upgrade, whereas 802.1X+AES may be implemented only after a hardware upgrade. An independent authentication server is required. WPA/WPA2-802.1X authentication applies to networks that require high security, such as enterprise networks. They have almost the same security level and mainly differ in the protocol packet format. If STAs support only WEP encryption, PSK+TKIP can be implemented without a hardware upgrade, whereas PSK+AES may be implemented only after a hardware upgrade.īoth WPA and WPA2 support 802.1X authentication and the TKIP or AES encryption algorithm.

WPA/WPA2-PSK authentication applies to individual, home, and Small Office and Home Office (SOHO) networks that do not require high security. Two authentication methods are available: WPA/WPA2-PSK authentication and WPA/WPA2-802.1X authentication.īoth WPA and WPA2 support PSK authentication and the TKIP or AES encryption algorithm. The WPA/WPA2 security policy involves four phases: link authentication, access authentication, key negotiation, and data encryption. With almost the same security level, they mainly differ in the protocol packet format. WPA2 uses a more secure encryption algorithm: Counter Mode with CBC-MAC Protocol (CCMP).īoth WPA and WPA2 support 802.1X access authentication and the TKIP or CCMP encryption algorithm, giving better compatibility. In addition to the RC4 algorithm, WPA defines the Temporal Key Integrity Protocol (TKIP) encryption algorithm on the basis of WEP, uses the 802.1X identity authentication framework, and supports Extensible Authentication Protocol-Protected Extensible Authentication Protocol (EAP-PEAP) and EAP-Transport Layer Security (EAP-TLS) authentication. The Wi-Fi Alliance developed WPA to overcome WEP defects.

Both the encryption mechanism and algorithm, however, are prone to security threats. Therefore, the same static key must be preconfigured on the server and clients. WEP shared key authentication uses the Rivest Cipher 4 (RC4) symmetric stream cipher to encrypt data.
