WEP和WPA的区别

1.有线等效保密(WEP)：
有线等效保密 (WEP) 是无线网络的安全协议，可提供与传统有线网络相当的数据保密性。它于 1999 年推出。它通过使用加密密钥提供无线安全性。它使用一种旧的加密方法，即 Rivest Cipher 4 (RC4)。它使用 40 位密钥和 24 位随机数。

2. Wi-Fi 保护访问 (WPA)：
Wi-Fi 保护访问 (WPA) 是一种安全协议，用于保护无线网络并旨在取代 WEP 协议。它由 Wi-Fi 联盟于 2003 年开发。它旨在取代 WEP 协议，并使用 Rivest Cipher 4 (RC4) 和临时密钥完整性协议 (TKIP) 进行加密。 WPA 密钥是 256 位密钥。

WEP和WPA的区别：

S.No.	WEP	WPA
01.	WEP stands for Wired Equivalent Privacy.	WPA stands for Wi-Fi Protected Access.
02.	It is a security protocol for wireless networks which provides data confidentiality comparable to a traditional wired network.	It is a security protocol which is used in securing wireless networks and designed to replace the WEP protocol.
03.	Wired Equivalent Privacy (WEP) was introduced in 1999 means before WPA.	Wi-Fi Protected Access (WPA) was developed by the Wi-Fi Alliance in 2003 means after WEP.
04.	It provides wireless security through the use of an encryption key.	It provides wireless security through the use of a password.
05.	Data Privacy (Encryption) method is Rivest Cipher 4 (RC4).	Data Privacy (Encryption) method is Rivest Cipher 4 (RC4) and Temporal Key Integrity Protocol (TKIP).
06.	Authentication method in WEP is Open system authentication or shared key authentication.	Authentication method in WPA is WPA-PSK and WPA-Enterprise.
07.	Data integrity is provided through CRC 32.	Data integrity is provided through Message integrity code.
08.	It uses 40 bit key and 24 bit random number.	WPA key is 256 bit key.
09.	Key management is not provided in WEP.	Key management is provided through 4 way handshaking mechanism.
10.	In WEP no protection against reply attacks.	In WPA sequence counter is implemented for reply protection.
11.	It is possible to deploy on current hardware infrastructure.	It is possible to deploy on both previous and current hardware infrastructure.
