Abstract
With the recent development and popularization of various network technologies, communicating with people at any time, and from any location, using high-speed internet, has become easily accessible. At the same time, eavesdropping, data interception, personal data leakage, and distribution of malware during the information transfer process have become easier than ever. Recently, to respond to such threats, end-to-end encryption (E2EE) technology has been widely implemented in commercial network services as a popular information security system. However, with the use of E2EE technology, it is difficult to check whether an encrypted packet is malicious in an information security system. A number of studies have been previously conducted on deep packet inspection (DPI) through trustable information security systems. However, the E2EE is not maintained when conducting a DPI, which requires a long inspection time. Thus, in this study, a fast packet inspection (FPI) and its frame structure for quickly detecting known malware patterns while maintaining E2EE are proposed. Based on the simulation results, the proposed FPI allows for inspecting packets approximately 14.4 and 5.3 times faster, respectively, when the inspection coverage is 20% and 100%, as compared with a DPI method under a simulation environment in which the payload length is set to 640 bytes.
Highlights
Due to the commercialization of smart electronic devices in recent years, numerous services and mobile applications that collect, process, and transfer personal and financial information have become popular [1]

Because fast packet inspection (FPI) supports adding the desired hash bitmaps (Hbm) components, which indicates the security of such inspection, it can be concluded that the FPI method is a more effective inspection technique than the DPI method in terms of the transmission time and security
Summary
Due to the commercialization of smart electronic devices in recent years, numerous services and mobile applications that collect, process, and transfer personal and financial information have become popular [1]. Information exchanges through networks, such as in smart working, remote meetings, and remote classes, are expected to drastically expand [3] Security issues such as eavesdropping, personal data leakage, privacy infringement, and malware distribution continuously occur during the process of data transmission over a network [4]. To address the issues of the existing techniques, in this paper, a fast packet inspection (FPI) method is proposed as a frame structure and transmission mechanism that can guarantee data integrity through an FPI in an E2EE environment while effectively detecting malware.
