Mobile applications increasingly handle sensitive operations, from payment authentication to digital identity verification, in environments that cannot be fully trusted. Even when an app is protected, attackers can still target the device, the operating system, or runtime processes to intercept data, manipulate logic, or bypass security controls. The Licel vTEE (Virtual Trusted Execution Environment) provides a secure, isolated environment - a bit like a secure vault - within the mobile app to protect sensitive operations at runtime. This ensures that critical data and logic remain protected even on compromised devices. The Licel vTEE creates a protected execution layer inside the application, allowing organizations to securely handle: • Cryptographic operations and key storage • Payment authentication and transaction processing • Digital identity and eKYC flows • Tokenisation and sensitive data processing Unlike traditional approaches that rely on device-specific hardware security (TEEs, Secure Enclaves), the Licel vTEE: • Works consistently across devices and operating systems • Does not depend on OEM implementations or availability • Gives full control to the application provider This makes it suitable for large-scale deployments where device fragmentation and inconsistent hardware security are a challenge. Designed for high-security and regulated use cases: The Licel vTEE is designed to support applications in payments, financial services, and digital identity, where protecting sensitive transactions and operations (and meeting strict security standards) is critical. The Licel vTEE works alongside application protection solutions like DexProtector: • DexProtector protects the application from reverse engineering and tampering • The Licel vTEE protects sensitive logic and data during execution Together, they provide a layered approach to securing mobile applications in real-world environments.
