论文提出的方案称为“深度包”(deep packet),可以处理网络流量分类为主要类别(如FTP和P2P)的流量表征,以及需要终端用户应用程序(如BitTorrent和Skype)识别的应用程序识别。与现有的大多数方法不同,深度报文不仅可以识别加密流量,还可以区分VPN网络流量和非VPN网络流量。网络架构基于CNN与SAE,能同时进行应用识别与流量类型...

1 BlindBox: Deep Packet Inspection Over Encrypted TrafficRaluca Ada Popa Joint work with: Justine Sherry, Chang Lan, Sylvia Ratnasamy UC Berkeley SIGCOMM 2015 2 Deep Packet Inspection (DPI)Intrusion detection/prevention Exfiltration In-network devices which inspect packet payloads to enforce policies...
The approach of Blind-Box is to perform the deep-packet inspection directly on the encrypted traffic. BlindBox realizes this approach through a new protocol and new encryption schemes. We demonstrate that BlindBox enables applications such as IDS, ex-filtration detection and parental filtering, and...
1.2 基于有效载荷或数据包检验(data packet inspection:DPI):原理是不同类型的网络流量之中有特定的字符流(也称之为指纹),只需要在数据包的任意位置匹配这些字符流,从而进行分类。 - 优点:简单快速,只需要检测网络流的前几个数据包。 - 缺点:方法仅适用于未加密的流量,且计算开销较大。 1.3 基于流量统计特征 ...
Dell's patented Reassembly-Free Deep Packet Inspection engine, a full-stack stream inspection technology scans SSL-encrypted traffic — including HTTPS, SMTPS, NNTPS, LDAPS, FTPS, TelnetS, IMAPS, IRCS, and POPS — and regardless of the port being used. The service decrypts SSL traffic, ...
In some countries, network operators employ deep packet inspection techniques to block certain types of traffic. For example, Virtual Private Network (VPN) traffic can be analyzed and blocked to prevent users from sending encrypted packets over such networks. ...
Using deep packet inspection in CyberTraffic analysis CSR 2021View publicationAbstract In recent years we have observed an escalation of cybersecurity attacks, which are becoming more sophisticated and harder to detect as they use more advanced evasion techniques and encrypted communications. The research...
In this paper we propose Pine, a new Privacy-preserving inspection of encrypted traffic protocol that (1) simplifies the preprocessing step of PrivDPI thus further reduces the computation time and communication overhead of establishing the TLS connection between a user and a server; (2) supports ...
