Compressing web traffic using standard GZIP is becoming both popular and challenging
due to the huge increase in wireless web devices, where bandwidth is limited. Security and …

In this paper we focus on the process of deep packet inspection of compressed web traffic.
The major limiting factor in this process imposed by the compression, is the high memory …

Deep Packet Inspection (DPI) is the most time and resource consuming procedure in
contemporary security tools such as Network Intrusion Detection/Prevention System …

Current security tools, using “signature-based” detection, do not handle compressed traffic,
whose market-share is constantly increasing. This paper focuses on compressed HTTP …

Opaque traffic, ie, traffic that is compressed or encrypted, incurs particularly high overhead
for deep packet inspection engines and often yields little or no useful information. Our …

In this paper, we investigate the current use of data compression in network services that are
at the core of modern web-based applications. While compression reduces network traffic, if …

In recent years, studies of DPI have been carried out actively. HTTP packets, which are a
kind of DPI target, include GZIP compressed packets, and multi-streamed GZIP compressed …

Compression side-channel attacks like CRIME and BREACH have made compression a
liability even though it is a powerful tool for improving efficiency. We present debreach, a …

Pattern matching is a fundamental approach to detect malicious behaviors and information
over Internet, which has been gradually used in high-speed network traffic analysis …
