Architectural Layers & Silicon Defenses

Layer 1: Mobile Silicon Secure Element (eSE / StrongBox) (Common Criteria EAL5+/EAL6+ Secure Chip): Generating private keys on-chip within smartphone hardware completely isolated from Android/iOS kernels.
Layer 2: Hardware Key Attestation Verification Engine (X.509 Certificate Chain & Root Validation): Verifying that client keys were generated inside genuine hardware secure elements signed by Google/Apple roots.
Layer 3: Mobile Payment & Tokenization Subsystem (EMV Payment Tokenization / DUKPT): Decoupling actual Primary Account Numbers (PAN) into encrypted payment tokens and dynamic CVVs.
Layer 4: Enterprise Mobile Banking & IAM API (OAuth 2.0 / FAPI 2.0 / Mutual TLS REST): Authenticating mobile app requests, authorizing high-value wire transfers, and issuing digital credentials.

Cryptographic Telemetry & Compliance: < 12 ms (Hardware Attestation Verification) | 100% (Hardware-Backed Key Guarantee) | Anti-Jailbreak (Hardware Cryptographic Integrity) | EAL5+/6+ (Mobile Silicon Certification)

Extending Enterprise Hardware Roots of Trust to the Mobile Edge

Mobile smartphones are now the primary endpoint for consumer banking, enterprise authentication, and digital credentials. MobileHSM bridges enterprise server-side HSM clusters with mobile on-chip hardware security features—Android StrongBox, Apple Secure Enclave, and GSMA-compliant Embedded Secure Elements (eSE)—delivering hardware-attested security across untrusted mobile operating systems.

Core Engineering Areas

Android StrongBox Hardware Attestation — Engineering backend verification systems to cryptographically validate Android hardware-backed keystores.
Apple Secure Enclave & DCAppAttest Integration — Server-side cryptographic verification of iOS Secure Enclave keys and application integrity.
Mobile Payment Tokenization & EMVCo Standards — Generating and validating payment cryptograms for contactless NFC and in-app mobile purchases.
