SCX introduces stateless KV-cache encoding, ensuring privacy without sacrificing performance. It uses novel encryption schemes like token permutation, redundant embedding, and Laplace noise injection to protect sensitive data during Transformer inference. This approach provides robust security guarantees, including differential privacy, while maintaining mathematical equivalence to plaintext inference, ensuring zero quality loss.
Key Advantages:
- Enhanced Privacy: User-controlled keys prevent cloud providers from reconstructing inputs or independently predicting next tokens.
- Superior Efficiency: Achieves orders of magnitude lower latency than traditional cryptographic or TEE-based methods.
- Hardware Agnostic: Designed for flexible deployment across various cloud environments and hardware configurations.
- Scalable: Supports large Transformer models (7B, 70B) and long context lengths with minimal communication overhead.
Experimental results demonstrate SCX's exceptional performance:
- Llama-7B Latency: Reduces prefill latency from 17s (Full-TEE) to just 36ms.
- Throughput: Achieves 10.3x speedup over Full-TEE for Llama-7B with longer contexts.
- Communication Cost: KB-level communication per token, enabling mobile device compatibility.
- Memory Efficiency: Integrates with KV-cache compression techniques for an 85% reduction in memory movement latency.
SCX is rigorously designed to withstand various attacks:
- Differential Privacy: Laplace noise ensures bounded information leakage, preventing brute-force and LLM-assisted recovery attacks.
- Statelessness Guarantee: Formal proof ensures the cloud cannot independently generate correct tokens without the user's key.
- Attack Resistance: Robust against brute-force vocabulary matching, LLM-assisted sequence recovery, and fitting-based inversion attacks.

Enterprise Use Case: Secure Medical Diagnostics AI
A leading healthcare provider deployed a Transformer model for medical diagnostics. Due to stringent patient privacy regulations (HIPAA, GDPR), cloud-based serving was a significant challenge. Implementing SCX allowed the provider to:
- Process sensitive patient data on cloud GPUs without exposing raw input or intermediate KV-cache to the cloud.
- Achieve inference latencies comparable to plaintext serving, crucial for real-time diagnostic support.
- Maintain full diagnostic accuracy, as SCX ensures mathematical equivalence to unencoded inference.
- Scale their AI operations globally, leveraging diverse cloud infrastructure without hardware vendor lock-in.
This resulted in a 50% reduction in privacy compliance overhead and a 30% improvement in diagnostic throughput.
