云计算与WPA体系安全研究

Cloud Computing and Research of WPA Security

无线局域网以无线信道作为传输媒介,广泛适用于需要可移动数据处理或无法进行物理传输介质布线的领域。但是其开放性特点使窃听、身份假冒和信息篡改等威胁无处不在。IEEE802.11协议提出了身份验证和数据加密等一系列安全机制来解决这些安全隐患,但是随着云计算的提出,面对每秒数亿次的超级计算平台,目前WLAN中的加密协议显得相形见拙。该文以WLAN中最常用的WPA加密协议为例,详细分析云计算对无线局域网安全带来的挑战,并用实验数据证明了这种安全威胁的真实性和严重性。

The WLAN with wireless channel for the transmission medium widely applied to the domain needing for removable data processing or unable to cabling with physics transmission medium. But its open characteristic causes wiretapping,identity threats, and so on counterfeiting and tampering of information are actually ubiquitous. The IEEE 802.11 proposes a series of safety mechanism to solves these Safety potential, as identification authentication and the data encryption and so on. But along with cloud computation, facing the supercomputing platform, computing hundreds of millions of times per second, the encryption protocol in WLAN became frail at present. In this paper based on the WLAN WPA encryption, a detailed analysis of cloud computing to WLAN security challenges will be discussed, finally the experimental data will prove the authenticity and severity of such security threat.
