求翻译：WEP 的数据完整性校验码也能同时用来检验接受到的数据包是否为用合法的RC4 算法加密，从而达到接入控制的目的。但校验码的计算并不是保密的，所以攻击者只要知道原文的某一片断以及该片断的密文，就可以避开校验码接入局域网内部。这是由于WEP 的接入控制是由校验码来检验数据包是否为正确的RC4 密钥流加密来实现的，所以如果能复原一个合法的密钥流，那么接入局域网就成为了可能。是什么意思？

wep data integrity check code can be used at the same time test received packet legal rc4 algorithm encryption, so as to achieve the purpose of access control. Checksum calculation is not confidential, so the attacker know the ciphertext of a fragment and the fragments of the original, you can avoid

The WEP data integrity verification code also can simultaneously use for the data packet which examines accepts whether for uses the legitimate RC4 algorithm encryption, thus achieves the turning on control the goal.But the verification code computation is not the security, therefore aggressor so lo

WEP data integrity checksum can be used to test both accept to whether the packet is encrypted with the RC4 algorithm of legitimate, so as to achieve the goal of access control. But the checksum calculation is not confidential, so an attacker need only know one of the fragments of the original text
