Zero Secrets Architecture for Mobile and API Security

This technical report presents the Zero Secrets Architecture as a modern approach to mobile application and API security, particularly in response to the evolving threat landscape characterized by agentic AI. It outlines the inadequacies of traditional security measures, such as code obfuscation and embedded secret hiding, which are no longer effective against sophisticated automated attacks. The report emphasizes the necessity of removing secrets from mobile applications, arguing that if secrets are not present, they cannot be exploited. It details the four pillars of a Zero Secrets Architecture: dynamic certificate pinning, cross-platform mobile app attestation, runtime secrets protection, and short-lived JWTs for API access. Additionally, it discusses advanced techniques like Token Binding and Message Signing to counter replay attacks. A practical adoption roadmap is provided, along with a checklist for Chief Information Security Officers to evaluate their organization's security posture. The report aims to shift the focus of mobile security from static defenses to dynamic, environment-based trust mechanisms.
