wep加密方式是什么

Wired Equivalent Privacy or WEP is a security protocol or algorithm which is created for the Wi-Fi or IEEE 802.11 wireless networks. Wireless is a protocol where the data is transmitted via air with electromagnetic signals. As the air is accessible for everyone near us everyone can access the signals and data easily by sniffing the air. We should protect which data by using encryption and standards. WEP is a protocol that simply authenticates and encrypts data for wireless networks.

Wired Equivalent Privacy或WEP是为Wi-Fi或IEEE 802.11无线网络创建的安全协议或算法。无线是一种协议，其中数据通过电磁信号通过空中传输。由于附近的每个人都可以通达空气，因此每个人都可以通过嗅探空气轻松访问信号和数据。我们应该使用加密和标准来保护哪些数据。 WEP是一种协议，可以简单地对无线网络的数据进行身份验证和加密。

WEP历史 (WEP History)

WEP was ratified as a Wi-Fi security standard in 1999 by IEEE. The first version of the WEP standard was not so secure and can be easily hacked with regular tools. According to the US export restrictions, 64-bit encryption was used. In 2003 Wi-Fi Alliance announced that WEP has been superseded by Wi-Fi Protected Access (WPA). In 2004, a more secure version called WPA2 became the IEEE 802.11i standard.

WEP在1999年被IEEE批准为Wi-Fi安全标准。 WEP标准的第一个版本不是那么安全，可以使用常规工具轻松地被入侵。根据美国的出口限制，使用了64位加密。 Wi-Fi联盟于2003年宣布，WEP已被Wi-Fi保护访问(WPA)取代。 2004年，更安全的版本称为WPA2成为IEEE 802.11i标准。

WEP加密 (WEP Encryption)

WEP security provides different functions like confidentiality, integrity, encryption. WEP uses RC4 for confidentiality and encryption and CRC-32 checksum for integrity. Standard 64-bit WEP uses a 40-bit key which is contaminated with a 23-bit initialization vector or IV.

WEP安全提供不同的功能，例如机密性，完整性，加密。 WEP使用RC4进行机密性和加密，并使用CRC-32校验和进行完整性。标准的64位WEP使用40位密钥，该密钥被23位初始化向量或IV污染。

WEP安全漏洞和问题 (WEP Security Vulnerabilities and Problems)

WEP is a very old protocol that goes back to 1997. At the time the WEP is released the security was not so important. With the advancement of the time, different vulnerabilities are found in the WEP and related protocols. The biggest security problem with WEP is its encryption algorithm RC4 which contains a security vulnerability that can be easily exploited. Especially IV can be cracked with the related key attack. Only using 5000 packets IV can be determined.

WEP是一个非常古老的协议，可以追溯到1997年。在发布WEP时，安全性并不那么重要。随着时间的推移，在WEP和相关协议中发现了不同的漏洞。 WEP的最大安全问题是其加密算法RC4，其中包含一个易于利用的安全漏洞。尤其是IV可以通过相关的密钥攻击来破解。只能确定使用5000个数据包IV。
