## Project Background and Security Challenges

With the widespread application of large language models (LLMs) in enterprise scenarios, security issues have become increasingly prominent. Enterprises face multiple risks when using LLM APIs:

## Prompt Injection Attacks

Attackers may embed malicious instructions in user inputs, attempting to make the model perform unintended operations, such as leaking system prompts, bypassing content security policies, or executing unauthorized data access.

## Sensitive Data Leakage

Users may inadvertently disclose personally identifiable information (PII), trade secrets, or regulated data in conversations. If this information is sent to third-party LLM service providers, it will pose serious compliance risks.

## Lack of Permission Control

Traditional API calls often lack fine-grained access control, making it difficult to implement differentiated model access strategies based on user roles, data sensitivity, or business scenarios.

## Data Sovereignty and Privacy

For industries with extremely high data security requirements such as finance, healthcare, and government, sending sensitive data to external cloud services may violate data localization or data sovereignty regulations.

The Zero Trust AI API project is designed to address these security challenges. It is not just a simple API wrapper, but a complete enterprise-grade security framework that introduces the zero-trust security concept into LLM inference endpoints.

## Core Security Architecture

The project adopts a layered defense security architecture, implementing strict security controls at each processing stage:
