Atoma Technical Architecture Report

​
Summary

Atoma represents a breakthrough in confidential computing infrastructure, delivering the industry’s first scalable platform that combines automated Kubernetes deployments, distributed ledger-based attestation, and composable encryption for enterprise AI workloads. This technical report details the core architectural components that enable Atoma to provide hardware-level security guarantees while maintaining cloud-native scalability and developer experience.

​
1. Automated Confidential Kubernetes Platform

​
1.1 Master Pod Architecture

Atoma’s Kubernetes deployment model centers around a sophisticated master pod architecture that orchestrates confidential computing resources: Master Pod Responsibilities:
  • Attestation Orchestration: Coordinates hardware attestation across all worker nodes
  • Key Management: Manages encryption key lifecycle and distribution
  • Security Policy Enforcement: Ensures compliance with defined security policies
  • Resource Allocation: Optimizes placement of confidential workloads based on hardware capabilities

​
1.2 Confidential Computing Integration

Trusted Execution Environment (TEE) Stack: Technical Implementation:
  • Memory Isolation: Hardware-enforced memory encryption with 256-bit AES keys
  • CPU State Protection: Register and cache isolation preventing side-channel attacks
  • Interrupt Handling: Secure interrupt virtualization within TEE boundaries
  • DMA Protection: IOMMU-based protection against DMA attacks

​
1.3 Kata Containers Deep Integration

Atoma leverages Kata Containers with custom modifications for enhanced security: Performance Optimizations:
  • Micro-VM Boot Time: Fast startup time for confidential containers
  • Memory Overhead: Lower overhead compared to standard containers
  • I/O Performance: Near-native disk and network performance through paravirtualization

​
1.4 GPU Operator Integration

NVIDIA Confidential Computing Integration:
  • GPU Memory Encryption: Hardware-based encryption of GPU memory contents
  • Secure Multi-Tenancy: Cryptographic isolation between GPU workloads
  • Attestation Integration: GPU hardware attestation integrated with broader platform attestation

​
1.5 Encrypted Messaging Infrastructure

Network Security Properties:
  • Perfect Forward Secrecy: Unique session keys for each communication session
  • Post-Quantum Cryptography: Quantum-resistant key exchange algorithms
  • Zero-Knowledge Networking: Network infrastructure cannot decrypt pod communications
  • Automatic Key Rotation: Session keys rotated on a periodic basis or upon certain threshold limit of data transfer

​
2. Atoma Registry: Distributed Ledger Infrastructure

​
2.1 Disributed Ledger-Based Attestation and Key Management

  • Distributed ledger technologies allow storing remote attestation and master encryption keys in an immutable and transparent way.
  • Creates a vehicle for auditing procedures, and build a full historical chain of trust.

​
2.2 Remote Attestation Verification Service

Attestation Verification at Scale:
  • Throughput: Can process a large number of attestation verifications per second
  • Latency: Low average verification time
  • Availability: 99.99% uptime SLA with automatic failover

​
2.3 Key Registration and Discovery

Encryption Key Lifecycle Management:
  • In order to safeguard sensitive workloads and avoid potential replay attacks from malicious actors, Atoma enforces key rotation management sessions, allowing cluster to rotate keys in a coordinated way, without affecting their underlying services. This process ensures a smooth rotation mechanism, increasing security guarantees without compromising availability and uptime.

​
3. Composable Encryption Architecture

​
3.1 Multi-Layered Data Protection

Encryption Layer Architecture:

​
3.2 Key Isolation and Management

​
4. High-Efficiency Deployment Architecture
