Overview

This document provides a comprehensive security analysis of the Solident wallet system, detailing the cryptographic protocols, threat models, and security measures implemented to protect user assets and privacy.

Executive Summary

Solident employs a multi-layered security architecture that combines biometric authentication, encrypted storage, and zero-trust protocols to protect user assets and privacy. Our security model is designed to protect against both external threats and insider risks while maintaining regulatory compliance.

Key Security Features

Encryption Standards

• AES-256-GCM: Symmetric encryption for all stored data

• RSA-4096: Asymmetric encryption for key exchange

• SHA-256: Cryptographic hashing for verification

• HMAC-SHA256: Message authentication codes

Biometric Security

• Local Face Processing: All biometric operations occur on-device

• Liveness Detection: Advanced anti-spoofing mechanisms

• Secure Template Storage: Encrypted biometric templates

• Zero-Knowledge Proofs: Cryptographic proof of identity

Network Security

• TLS 1.3: End-to-end encryption for all communications

• Certificate Pinning: Prevents man-in-the-middle attacks

• Rate Limiting: Protection against brute force attacks

• DDoS Protection: Multi-layer network defenses

Threat Model

External Threats

• Man-in-the-Middle Attacks: Prevented by TLS and certificate pinning

• Device Compromise: Mitigated by hardware security modules

• Social Engineering: Addressed through user education and MFA

• Phishing Attacks: Protected by domain verification and security headers

Internal Threats

• Insider Attacks: Prevented by zero-knowledge architecture

• Data Breaches: Protected by encryption and access controls

• Privilege Escalation: Mitigated by principle of least privilege

• Supply Chain Attacks: Addressed through code signing and audits
