Security Features
🔐 Encryption
End-to-end encryption using industry-standard protocols (TLS/SSL) to protect update packages during transmission and storage.
✅ Digital Signatures
Cryptographic signature verification ensures updates are authentic and unmodified before installation.
🛡️ Integrity Checks
Hash verification (SHA-256, SHA-512) and checksum validation at multiple stages to ensure update integrity.
🔒 Access Control
Role-based access control and authentication mechanisms to prevent unauthorized update attempts.
Application Areas
IoT Devices
Remote firmware updates for connected IoT devices, sensors, and smart home appliances deployed in the field.
