WEP和WPA之间的区别

1.有线等效保密(WEP)：
有线等效保密(WEP)是用于无线网络的安全协议，可提供与传统有线网络相当的数据机密性。它于1999年推出。它通过使用加密密钥来提供无线安全性。它使用的是Rivest Cipher 4(RC4)的旧加密方法。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，旨在取代WEP协议。它是由Wi-Fi联盟于2003年开发的。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之间的区别：

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.
