+- **Cryptographically secure** key pair generation
+- **Perfect Forward Secrecy** with session-specific keys
+- **MITM resistance** requiring knowledge of both private keys
+
+**Technical Details:**
+```javascript
+// ECDH Key Generation
+const keyPair = await crypto.subtle.generateKey(
+ { name: 'ECDH', namedCurve: 'P-384' },
+ true,
+ ['deriveKey', 'deriveBits']
+);
+
+// Shared Secret Derivation
+const sharedSecret = await crypto.subtle.deriveBits(
+ { name: 'ECDH', public: peerPublicKey },
+ privateKey,
+ 384
+);
+```
+
+### 3. DTLS Fingerprint Verification
+
+**New Features:**
+- **WebRTC Certificate Extraction** from SDP offers/answers
+- **SHA-256 Fingerprint Generation** for transport verification
+- **Mutual Verification** between both parties
+- **Transport Layer Security** validation
+
+**Security Properties:**
+- ✅ **Connection Integrity** - Prevents hijacking
+- ✅ **Certificate Validation** - Ensures authentic WebRTC certificates

+- **HKDF-based Generation** from shared secret and DTLS fingerprints
+- **Single Code Generation** on Offer side, shared with Answer side
+- **Mutual Verification** - Both users must confirm the same code
+
+**Implementation:**
+```javascript
+// SAS Generation
+async _computeSAS(keyMaterialRaw, localFP, remoteFP) {
+ const salt = enc.encode('webrtc-sas|' + [localFP, remoteFP].sort().join('|'));
+ const key = await crypto.subtle.importKey('raw', keyMaterialRaw, 'HKDF', false, ['deriveBits']);
+ const bits = await crypto.subtle.deriveBits(
+ { name: 'HKDF', hash: 'SHA-256', salt, info: enc.encode('p2p-sas-v1') },
+ key, 64
+ );
+ const n = (new DataView(bits).getUint32(0) ^ new DataView(bits).getUint32(4)) >>> 0;
+ return String(n % 10_000_000).padStart(7, '0');
+}
+```
+
+---
+
+## 🔒 Security Flow
+
+### New Authentication Process
+
+```
+1. ECDH Key Exchange
+ ├── Generate P-384 key pairs
+ ├── Exchange public keys via SDP
+ └── Derive shared secret
+
+2. DTLS Fingerprint Verification
+ ├── Extract certificates from WebRTC SDP
+ ├── Generate SHA-256 fingerprints
+ └── Verify transport authenticity
+
+3. SAS Generation and Sharing
+ ├── Generate SAS from shared secret + fingerprints
+ ├── Share SAS code via data channel
+ └── Display to both users
+
+4. Mutual Verification
+ ├── Both users confirm the same SAS code
+ ├── Connection established only after confirmation
+ └── Secure communication begins
+```
+
+### MITM Attack Prevention
+
+**Triple-Layer Defense:**
+1. **ECDH Layer** - Requires knowledge of both private keys
+2. **DTLS Layer** - Validates transport layer certificates
+3. **SAS Layer** - Human-verifiable out-of-band confirmation
+
+**Attack Scenarios:**
+- ❌ **Passive Eavesdropping** - Prevented by ECDH encryption
+- ❌ **Active MITM** - Prevented by DTLS fingerprint verification
+- ❌ **Certificate Spoofing** - Prevented by SAS verification
+- ❌ **Connection Hijacking** - Prevented by mutual verification
+
+---
+
+## 🚀 Performance Improvements
+
+### Reduced Dependencies

+- **After:** Native Web Crypto API (0KB additional)
+- **Improvement:** ~200KB reduction in bundle size
+
+### Faster Authentication
+- **Before:** Complex PAKE multi-step protocol
+- **After:** Streamlined ECDH + SAS verification

+## 🛡️ ECDH + DTLS + SAS Security System
+
+### Overview
+
+SecureBit.chat v4.02.985 introduces a revolutionary three-layer security system that eliminates traditional PAKE-based authentication in favor of a more robust and standardized approach:
+
+1. **ECDH (Elliptic Curve Diffie-Hellman)** - Secure key exchange
+2. **DTLS Fingerprint Verification** - Transport layer security validation
+3. **SAS (Short Authentication String)** - MITM attack prevention
+
+### ECDH Key Exchange
+
+**Purpose:** Establish a shared secret between two parties without prior knowledge
+
+**Implementation:**
+- **Curve:** P-384 (secp384r1) for maximum security
+- **Key Generation:** Cryptographically secure random key pairs
+- **Shared Secret:** Derived using ECDH protocol
+- **Key Material:** Used for subsequent encryption and authentication
+
+**Security Properties:**
+- **Forward Secrecy:** Each session uses unique key pairs
+- **Perfect Forward Secrecy:** Past sessions cannot be compromised
+- **MITM Resistance:** Requires knowledge of both private keys
+
+### DTLS Fingerprint Verification
+
+**Purpose:** Verify the authenticity of the WebRTC transport layer
+
+**Implementation:**
+- **Certificate Extraction:** From WebRTC SDP offers/answers
+- **Fingerprint Generation:** SHA-256 hash of the certificate
+- **Verification:** Both parties verify each other's DTLS fingerprints
+- **Transport Security:** Ensures connection is not intercepted
+
+**Security Properties:**
+- **Transport Integrity:** Prevents connection hijacking
+- **Certificate Validation:** Ensures authentic WebRTC certificates
+- **MITM Detection:** Detects man-in-the-middle at transport layer
+
+### SAS (Short Authentication String)
+
+**Purpose:** Provide out-of-band verification to prevent MITM attacks
+
+**Implementation:**
+- **Generation:** HKDF-based derivation from shared secret and DTLS fingerprints
+- **Format:** 7-digit numeric code (0000000-9999999)
+- **Sharing:** Generated once on Offer side, shared with Answer side
+- **Verification:** Both users must confirm the same code
+
+**Security Properties:**
+- **MITM Prevention:** Requires attacker to know the shared secret
+- **User Verification:** Human-readable verification step
+- **Standard Compliance:** Follows RFC 5763 recommendations
+
+### Security Flow
+
+```
+1. ECDH Key Exchange
+ ├── Generate key pairs (P-384)
+ ├── Exchange public keys
+ └── Derive shared secret
+
+2. DTLS Fingerprint Verification
+ ├── Extract certificates from SDP
+ ├── Generate SHA-256 fingerprints
+ └── Verify transport authenticity
+
+3. SAS Generation and Verification
+ ├── Generate SAS from shared secret + fingerprints
+ ├── Share SAS code between parties
+ └── Mutual verification by both users
+
+4. Connection Establishment
+ ├── All three layers verified
+ ├── Secure channel established
+ └── Communication begins
+```
+
+### Advantages Over PAKE
+
+| Aspect | PAKE (Previous) | ECDH + DTLS + SAS (Current) |
+|--------|-----------------|------------------------------|
+| **Dependencies** | libsodium required | Native Web Crypto API |
+| **Standards** | Custom implementation | RFC-compliant protocols |
+| **MITM Protection** | Single layer | Triple-layer defense |
+| **User Experience** | Password-based | Code-based verification |
+| **Security** | Good | Military-grade |
+| **Maintenance** | Complex | Simplified |
+
+### Implementation Details
+
+**Key Components:**
+- `_computeSAS()` - SAS generation using HKDF
+- `_extractDTLSFingerprintFromSDP()` - Certificate extraction
+- `_decodeKeyFingerprint()` - Key material processing
+- `confirmVerification()` - Mutual verification handling
+
+**Security Considerations:**
+- **Timing Attacks:** Constant-time operations
+- **Side Channels:** No information leakage
+- **Replay Protection:** Unique session identifiers
+- **Forward Secrecy:** Session-specific keys
