XRAY Completely Hides Traffic, Functioning as an Anti-DPI Technology
DPI (Deep Packet Inspection)
DPI (Deep Packet Inspection) is a deep packet analysis technology used by internet service providers, governments, corporate networks, and other censors.
DPI enables:
1. Identifying traffic type and activity, such as whether you’re streaming videos, gaming, using a VPN, or simply browsing the web. 2. Detecting VPN or proxy usage, as well as logging all technical characteristics of such connections, even if they are encrypted. 3. Restricting or blocking access to specific websites, applications, or services, even when using classical VPN protocols like WireGuard or OpenVPN.
What does XTLS Reality do?
XTLS Reality effectively counters all these challenges by masking traffic as standard HTTPS connections, making it indistinguishable from regular HTTPS traffic to observers. This means that even advanced monitoring and surveillance systems cannot determine what you are doing online—whether streaming videos, making voice calls, downloading files, or chatting.
This is achieved through:
1. Traffic masking as HTTPS
Standard HTTPS connections use the TLS protocol to encrypt data. XTLS Reality structures its handshake and data exchange to be indistinguishable from legitimate HTTPS connections by accurately replicating all patterns and behaviors of regular TLS.
2. Adaptive behavior
The XRAY server analyzes incoming requests from DPI systems and adjusts its behavior to always appear as standard HTTPS traffic. If a traffic observer attempts to perform an “active test,” the protocol either correctly rejects the attempt or redirects it to a decoy website.
3. Metadata concealment
In standard protocols like WireGuard or OpenVPN, metadata (such as connection times and port numbers) can be used to identify VPN usage. XRAY removes unnecessary signatures from the connection that might reveal it as something other than HTTPS. Even if DPI systems attempt to compare this data with known VPN protocol patterns, the result indicates “normal traffic.
4. Header encryption
Most standard protocols leave headers exposed, even if the payload is encrypted. These headers can provide DPI systems with clues. XTLS Reality encrypts headers as well, maintaining compatibility with the HTTPS format. Conclusion XRAY effectively combats advanced traffic and VPN blocking systems while significantly enhancing your privacy and security online. It offers superior protection compared to classical VPN protocols like WireGuard and OpenVPN.
