3GPP MCP Server

# Complete Workflow: Researching 5G Authentication **Scenario**: You've been assigned to understand and potentially implement 5G authentication for your project. You know it's important for security, but you're not sure where to start or what exactly you need to learn. **Goal**: By the end of this workflow, you'll have a clear understanding of 5G authentication, know which specifications to study, and have a practical implementation roadmap. **Time Investment**: 2-3 hours for complete workflow, immediate value within 15 minutes --- ## Before We Start: Traditional vs MCP-Guided Approach ### ❌ Traditional Approach Problems: - Google "5G authentication" → Get overwhelmed by 500+ page specs - Try to read TS 33.501 from page 1 → Get lost in architectural details - Find random blog posts → Get incomplete or outdated information - Attempt implementation → Make costly mistakes due to missing context ### ✅ MCP-Guided Approach Benefits: - Get expert research methodology immediately - Receive structured learning path optimized for comprehension - Access implementation guidance with specific sections - Avoid common pitfalls that waste time and create bugs --- ## Step 1: Initial Query - Get Your Research Strategy 🎯 ### What to Ask the MCP Server: ``` I need to understand 5G authentication for a project. I'm an experienced developer but new to 3GPP specifications. Can you give me a strategic learning approach that will help me understand both the theory and implementation requirements? ``` ### What You'll Get Back: The MCP server will analyze your query and provide: - **Structured learning path** tailored to your experience level - **Specific specification sections** to read in optimal order - **Key concepts** you need to master at each stage - **Implementation considerations** for practical application - **Estimated timeframes** for each learning phase ### Example Response Structure: ```markdown # Strategic Learning Path for 5G Authentication ## Phase 1: Foundation Building (Day 1-2) **Start with architecture understanding:** - TS 33.501 Section 6: 5G security architecture overview - Key entities: UE, AUSF, SEAF, UDM - understand their roles - Create a diagram: Visual map of authentication flow ## Phase 2: Detailed Procedures (Day 3-5) **Study the step-by-step processes:** - TS 24.501 Section 4.2: Authentication procedures - Focus concepts: SUCI vs SUPI, 5G-AKA process, key derivation - Hands-on: Trace through complete message flows ## Phase 3: Implementation Requirements (Day 6-7) **For practical application:** - TS 33.501 Annex A: Cryptographic algorithms - Implementation components: SUCI generation, key derivation - Testing strategies: Validation approaches ``` --- ## Step 2: Deep Dive into Architecture 🏗️ ### Follow-up Query: ``` I want to understand the 5G security architecture first. Can you guide me through TS 33.501 Section 6 and explain how the different entities (UE, AUSF, SEAF, UDM) work together in authentication? ``` ### What You'll Learn: The MCP server will provide: - **Entity roles and responsibilities** clearly explained - **Interface descriptions** between security functions - **Message flows** with step-by-step explanations - **Key concepts** like security anchoring and authentication vectors - **Visual guidance** on creating your own architecture diagrams ### Practical Exercise: After getting the MCP guidance, create a simple diagram showing: - UE connecting to SEAF (in AMF) - SEAF communicating with AUSF - AUSF coordinating with UDM - Key derivation happening at each step --- ## Step 3: Understanding Key Concepts 🔑 ### Next Query: ``` I'm reading about SUCI and SUPI in the authentication process. Can you explain the difference, why SUCI is needed, and how the privacy protection mechanism works? ``` ### What You'll Understand: - **SUPI (Subscription Permanent Identifier)**: The actual subscriber identity - **SUCI (Subscription Concealed Identifier)**: Privacy-protected version - **Why SUCI matters**: Prevents IMSI catching and tracking - **How concealment works**: Public key encryption with operator keys - **Implementation requirements**: ECIES encryption with P-256 curve ### Real-World Context: The MCP server will explain why this matters: - Privacy regulations compliance - Security against passive attacks - Implementation in different deployment scenarios --- ## Step 4: Protocol Procedures Deep Dive 📋 ### Query for Detailed Understanding: ``` Now I want to understand the actual 5G-AKA authentication procedure step by step. Can you walk me through TS 24.501 Section 4.2 and explain what happens in each message exchange? ``` ### What You'll Get: **Step-by-step procedure breakdown:** 1. Authentication request with SUCI 2. Authentication challenge generation 3. UE response calculation 4. Network verification and key derivation 5. Security context establishment **For each step, you'll understand:** - Exact message formats and contents - Cryptographic operations performed - Error conditions and handling - Timing requirements and constraints ### Hands-On Activity: Use the MCP guidance to trace through a complete authentication: - Start with a sample SUCI - Follow the challenge-response process - Track key derivation at each stage - Understand final security context --- ## Step 5: Implementation Planning 🔧 ### Implementation-Focused Query: ``` I need to implement 5G authentication in our system. Can you provide specific implementation guidance including which components to build, in what order, and common pitfalls to avoid? ``` ### What You'll Receive: **Implementation roadmap:** - Components to build (SUCI generator, key derivation, message handlers) - Development sequence (start with simplest, add complexity) - Testing approach (unit tests with spec test vectors) - Integration strategy (how components work together) **Critical implementation details:** - Algorithm specifications and test vectors - Error handling requirements - Performance considerations - Security requirements and validation --- ## Step 6: Validation and Testing 🧪 ### Testing Strategy Query: ``` How should I validate my 5G authentication implementation? What test vectors and conformance tests are available? ``` ### What You'll Learn: **Testing methodology:** - Unit testing with specification test vectors - Integration testing with test USIM data - Conformance testing against standard test cases - Interoperability testing considerations **Specific test resources:** - Where to find official test vectors - How to set up test environments - Common test scenarios to validate - Performance benchmarks and targets --- ## Step 7: Advanced Topics and Next Steps 🚀 ### Advanced Learning Query: ``` I understand basic 5G authentication now. What are the advanced topics I should study next to become an expert in 5G security? ``` ### Advanced Topics Guidance: - **Network slicing security**: Authentication in multi-tenant scenarios - **Roaming authentication**: Inter-operator security procedures - **Secondary authentication**: Application-specific authentication - **Privacy mechanisms**: Advanced identity protection - **Post-quantum cryptography**: Future-proofing considerations --- ## Complete Timeline: Your 7-Day Learning Plan 📅 ### Day 1: Architecture Foundation - **Morning**: Query MCP for learning strategy - **Afternoon**: Study TS 33.501 Section 6 with MCP guidance - **Exercise**: Create architecture diagram - **Outcome**: Clear understanding of security entities ### Day 2: Key Concepts Deep Dive - **Morning**: SUCI/SUPI concepts with MCP explanation - **Afternoon**: Study privacy protection mechanisms - **Exercise**: Understand ECIES encryption process - **Outcome**: Master identity protection concepts ### Day 3-4: Protocol Procedures - **Day 3**: 5G-AKA procedure with step-by-step MCP guidance - **Day 4**: Message flows and error handling - **Exercise**: Trace complete authentication sequence - **Outcome**: Detailed protocol understanding ### Day 5-6: Implementation Planning - **Day 5**: Implementation roadmap from MCP server - **Day 6**: Component design and architecture - **Exercise**: Design your implementation approach - **Outcome**: Ready-to-code implementation plan ### Day 7: Testing and Validation - **Morning**: Testing strategy from MCP guidance - **Afternoon**: Set up test environment - **Exercise**: Plan validation approach - **Outcome**: Complete implementation and testing plan --- ## Real Queries You Can Try Right Now 💪 Copy these exact queries to your MCP-enabled AI assistant: ### Starter Queries: ``` 1.
