Suggestions for Enhancement & Improvements
Hi @MHSanaei First of all, we want you to know that we genuinely appreciate your efforts and hard work. Thank you for shouldering these burdens with strength and dedication.
Here are a few suggestions. While some may already be in practice, I wanted to share these ideas for brainstorming and bringing new concepts & ideas to the table
Traffic & Packet Padding:
Packet padding adds random data to your packets, making the traffic less predictable and harder to fingerprint.
"settings": {
"padding": {
"type": "random",
"length": 64
}
}
Connection Pacing:
Introduce connection pacing to limit the rate at which new connections are established, preventing detection based on connection patterns.
"settings": {
"trafficPacing": {
"enable": true,
"rate": 500
}
}
Connection Pooling:
Utilize connection pooling to reuse existing connections, reducing connection setup overhead and improving performance.
{
"settings": {
"pooling": {
"enabled": true,
"maxIdle": 30 // Adjust as needed
}
},
"tag": "pooled"
}
Randomize Connection Parameters:
Introduce randomness to connection parameters such as connection timeouts, retries, and delays. This can make your traffic less predictable and harder to fingerprint.
"settings": {
"timeout": 300, // Randomize timeout values
"keepAlive": 60, // Randomize keep-alive values
// Add more parameters for randomization as needed
}
Session Resumption:
Enable session resumption to reduce the overhead of establishing new connections, improving connection speed.
{
"protocol": "tls",
"settings": {
"sessionResumption": true
},
"tag": "resumable"
}
Session Resumption:
Implement session resumption to reduce latency and improve performance.
"settings": {
"session": {
"enable": true,
"cacheSize": 100
}
}
Anti-Replay Mechanism:
Implement an anti-replay mechanism to prevent attackers from intercepting and retransmitting your encrypted traffic.
"settings": {
"antiReplay": true
}
Encrypted SNI (Server Name Indication):
Encrypt the Server Name Indication to prevent eavesdroppers from inspecting the destination server.
"settings": {
"sni": "encrypted"
}
Encrypted SNI (ESNI):
Use Encrypted Server Name Indication (ESNI) to encrypt the SNI field in TLS connections, enhancing privacy.
"outbounds": [
{
"protocol": "tls",
"settings": {
"serverName": "encrypted-domain.com",
"esni": true
},
"tag": "encrypted-sni"
}
]
Rate Limiting:
Implement rate limiting to prevent abuse and potential denial-of-service attacks. Adjust the values of downlinkCapacity and uplinkCapacity based on your expected traffic patterns.
"inbounds": [
{
"listen": "127.0.0.1",
"port": 62789,
"protocol": "dokodemo-door",
"settings": {
"address": "127.0.0.1",
"network": "tcp,udp",
"downlinkCapacity": 1000000, // ←
"uplinkCapacity": 1000000 // ←
},
"tag": "api"
}
],
Protocol Multiplexing:
Combine multiple protocols within a single connection to make it more difficult for network analyzers to identify the underlying communication.
"streamSettings": {
"network": "tcp",
"tcpSettings": {
"header": {
"type": "http",
"request": {
"version": "1.1",
"method": "GET",
"path": ["/", "/other-path"]
},
"response": {
"version": "1.1",
"status": "200",
"reason": "OK",
"headers": {
"Content-Type": ["application/octet-stream", "application/x-msdownload", "text/html", "application/x-shockwave-flash"]
}
}
}
}
},
Dynamic Port Knocking:
Implement dynamic port knocking as an additional layer of security. This involves a sequence of connection attempts to predefined ports to open access to the desired service.
// Add dynamic port knocking rules to your firewall settings
// Example using iptables
"firewall": {
"outbound": {
"port": "12345,54321,98765", // Define your port knocking sequence
"protocol": "tcp"
}
},
Payload Encryption with Perfect Forward Secrecy (PFS):
Use Perfect Forward Secrecy to generate unique encryption keys for each session, preventing retroactive decryption even if one key is compromised.
"streamSettings": {
"security": "tls",
"tlsSettings": {
"alpn": ["h2", "http/1.1"],
"certificates": ["/path/to/your/certificate.crt", "/path/to/your/private-key.key"],
"keyExchanges": ["ECDHE", "DHE"]
}
},
Fake Traffic Generation:
Generate fake or decoy traffic to confuse adversaries and make it harder to distinguish real traffic.
"outbounds": [
{
"protocol": "http",
"settings": {
"servers": [
{
"address": "legitimate-server.com",
"port": 443
},
{
"address": "decoy-server.com",
"port": 443
}
]
},
"tag": "fake-traffic"
}
]
Behavioral Anomalies:
Introduce intentional behavioral anomalies in the traffic patterns to deter analysis.
"settings": {
"anomalies": {
"enable": true,
"pattern": "randomized"
}
}
Dynamic Obfuscation Parameters:
Change obfuscation parameters dynamically at runtime to prevent signature-based detection.
"plugin_opts": "obfs=http;obfs-host=www.dynamic-domain1.com;obfs-uri=/path1"
Rotate Encryption Keys:
If your application supports it, regularly rotate encryption keys. This adds an extra layer of security by limiting the exposure of a single key.
"settings": {
"keyRotationInterval": 86400 // Rotate keys every 24 hours
}
Domain Fronting:
Implement domain fronting to make the traffic appear as if it's going to a different domain. Note that not all networks and services support domain fronting.
{
"domain": ["example.com"],
"outboundTag": "fronted",
"type": "field"
}
Randomized DNS Queries:
Randomize the timing and order of your DNS queries to make it harder to profile your network behavior.
"dns": {
"queryStrategy": "randomized"
}
Add Security to DNS Configuration:
Ensure that the DNS queries are secure by using DNS over HTTPS (DoH) or DNS over TLS (DoT). This adds an additional layer of encryption to your DNS queries.
"dns": {
"servers": [
"https://1.1.1.1/dns-query",
"https://1.0.0.1/dns-query",
"https://[2606:4700:4700::1113]/dns-query",
"https://[2606:4700:4700::1003]/dns-query"
],
"queryStrategy": "UseIP"
}
Dynamic Routing
Dynamically change the routing paths for your traffic to make it more unpredictable.
"routing": {
"dynamicRouting": true
}
Noise Generation:
Introduce noise into your network traffic to make it more challenging for traffic analysis.
"settings": {
"noiseGeneration": true
}
IP Whitelisting:
Configure your VPS to only accept incoming traffic from whitelisted IP addresses, adding an extra layer of access control.
"policy": {
"levels": {
"0": {
"statsUserDownlink": true,
"statsUserUplink": true,
"ipWhitelist": ["trusted-ip1", "trusted-ip2"]
}
}
}
Honeypot Triggers:
Implement triggers that activate honeypot-like responses in the presence of certain detection attempts.
"settings": {
"honeypotTriggers": {
"enable": true,
"threshold": 3
}
}
Randomized Time Delays:
Introduce randomized time delays between connections to reduce predictability.
"settings": {
"timeDelays": {
"enable": true,
"minDelay": 100,
"maxDelay": 500
}
}
Zero-Knowledge Proof Authentication:
Implement zero-knowledge proof authentication to ensure that even the server does not learn the client's credentials.
"outbounds": [
{
"protocol": "vmess",
"settings": {
"zeroKnowledgeProof": true
},
"tag": "zkp-auth"
}
]
Quantum-Secure Encryption:
Utilize encryption algorithms specifically designed to be secure against quantum computing attacks.
"outbounds": [
{
"protocol": "tls",
"settings": {
"cipherSuites": ["quantum-secure-cipher1", "quantum-secure-cipher2"]
},
"tag": "quantum-secure-tls"
}
]
Post-Quantum Key Exchange:
Implement post-quantum key exchange mechanisms for securing communication channels.
"outbounds": [
{
"protocol": "tls",
"settings": {
"keyExchange": "post-quantum-key-exchange"
},
"tag": "post-quantum-tls"
}
]
Self-Destructing Connections:
Configure connections to self-destruct after a predefined period to minimize the risk of prolonged exposure.
"settings": {
"selfDestruct": {
"enable": true,
"timeout": 300
}
}
IPv6 Transition Techniques:
Implementing IPv6 transition techniques, such as Dual-Stack: These Linux commands are used to enable Dual-Stack on a network interface, allowing the system to support both IPv4 and IPv6 simultaneously
# Linux commands for enabling Dual-Stack on a network interface
sudo sysctl -w net.ipv6.conf.all.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=0
sudo sysctl -w net.ipv6.conf.eth0.disable_ipv6=0

"cipherSuites": ["quantum-secure-cipher1", "quantum-secure-cipher2"]
proxy cores are using standard tls ciphersuites to hide in it, if they add new ciphers to TLS's supported ciphersuites, they will get detected and blocked easily
Hi @APT-ZERO,
Thanks for the input! As I've mentioned earlier, these are just some ideas for brainstorming and introducing new concepts and strategies to the table.
Most of these suggestions need to be tested in real life to see what can be implemented or tweaked in the X-UI code. It's possible that some ideas might overlap or intersect with existing architecture in the X-UI core.
However, that's precisely why these ideas were suggested—to encourage people like yourself to come up with solutions and creative ideas to see what can be added and implemented.
In short, if we don't try, we'll never know what's possible. Hope that clears things up, dude.
PS: Here's some information on Quantum-Secure Encryption for network traffic. Hope that helps!

-
"cipherSuites": ["quantum-secure-cipher1", "quantum-secure-cipher2"] is not a valid syntax for specifying TLS cipher suites. TLS cipher suites are typically represented using standardized names or identifiers, such as "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384" or "0xc030".
-
The term "quantum-secure-cipher" is not a standard or recognized cipher suite name in the TLS protocol. Quantum-resistant or quantum-safe ciphers are still in the research and standardization phase, and they have not been officially integrated into the TLS protocol yet.
-
Proxy cores (assuming you mean proxy servers or proxy software) do not necessarily use standard TLS cipher suites to "hide" themselves. Proxy servers can use any of the supported cipher suites in the TLS protocol, just like any other client or server application.
-
If new cipher suites were to be added to the TLS protocol, they would not necessarily be detected or blocked easily. The process of adding new cipher suites to the TLS protocol involves standardization, implementation by various software vendors, and gradual adoption by clients and servers. It is a controlled process, and legitimate new cipher suites would not be automatically blocked.
