摘要
深度包检测技术通过对数据包内容的深入扫描和检测,能够有效识别出隐藏在数据包有效载荷内的非法数据,但该技术存在功耗非常大的缺点。针对该问题,提出了采用Bloom Filter(布隆过滤器)进行字符串模糊匹配方式,利用Bloom Filter将信息流中大部分正常流量过滤掉,从而减轻了后端的字符串精确匹配的压力,降低了系统功耗,大大提高了处理速度。
Based on depth scanning and detection for packet payload, deep packet inspection technology can effectively identify the hidden illegal data inside the packet payload, but the technology has the defect of large power consumption. In order to solve this problem, this paper presents string fuzzy matching method using Bloom filter. Using Bloom Filter in most of the normal of information flow is filtered, thus reducing the pressure of the exact string matching, reducing the power consumption of the system, and improving greatly the processing speed.
