Key Features
Roru One combines several critical security and functionality features that set it apart from software-only solutions. The device is built around a hardware secure element that provides the foundation for all security operations.
Hardware Secure Element:
The secure element is a dedicated cryptographic processor that operates independently from the main device processor. This isolation ensures that cryptographic keys are stored in tamper-resistant hardware and never exposed to the operating system or applications. The secure element handles all key storage, cryptographic operations, and hardware random number generation, providing a secure foundation for all device operations.

Hardware Components
Secure Element
The secure element is the heart of Roru One's security architecture. It's a specialized hardware component designed specifically for cryptographic operations and key management.
What It Is:
The secure element is a dedicated cryptographic processor that operates completely independently from the device's main processor. This physical separation ensures that even if the main processor is compromised, the cryptographic keys remain protected. The secure element uses tamper-resistant design principles, making it extremely difficult to extract information through physical attacks.

Security Features
Tamper Detection
Roru One includes sophisticated tamper detection mechanisms that monitor the physical integrity of the device. If any tampering is detected, the device automatically takes protective measures to prevent key extraction.
Physical Tamper Mesh:
The tamper mesh is a physical security layer that monitors various environmental factors to detect attempts to physically access the device's internals. It continuously monitors voltage, temperature, and frequency patterns that would indicate tampering.

Secure Boot
Secure boot ensures that only verified, authentic firmware can run on the device. This prevents attackers from installing malicious firmware that could compromise security.
Verified Firmware:
The secure boot process cryptographically verifies the firmware before allowing it to execute. Only firmware signed by Roru Labs can boot, creating a chain of trust from the hardware to the software.

Integration with Roru Wallet
Pairing Process
Pairing Roru One with your wallet establishes a secure, encrypted connection that allows the wallet to request transaction signatures from the hardware device. The pairing process uses cryptographic protocols to ensure that only authorized devices can communicate.
How It Works:
The pairing process begins from the wallet application, which initiates a secure connection request. Roru One generates a unique pairing code that must be confirmed on both devices, ensuring that the connection is established intentionally and securely.

Usage
Once paired, Roru One integrates seamlessly with the wallet for transaction signing, while also maintaining the ability to operate completely independently when needed.
Transaction Signing:
When using Roru One with a wallet, the wallet creates the transaction details and sends them to Roru One for signing. The device displays the transaction details on its interface (if available) or communicates them through the wallet, allowing you to verify before signing. Once signed in the secure element, the signed transaction is returned to the wallet for broadcast.
