Trezor Bridge

The official wallet's GitBook has announced that an update for Trezor Suite (version 22.9.3) is now available for installation. To proceed, simply download and apply the update.

Trezor Bridge implements several security features to ensure safe communication between the Trezor hardware wallet and the computer:

1. Secure Connection: Trezor Bridge establishes a secure connection between the web browser and the Trezor hardware wallet using the USB connection. This connection is encrypted using cryptographic protocols, such as Transport Layer Security (TLS) or Secure Socket Layer (SSL), to protect sensitive data transmitted between the device and the computer from interception or tampering by malicious actors.

2. Authentication: Before initiating communication with the Trezor hardware wallet, Trezor Bridge verifies the authenticity of the device to ensure that it has not been tampered with or replaced by a malicious counterfeit. This authentication process helps prevent unauthorized access to the device and ensures that only legitimate Trezor hardware wallets can communicate with the computer.

3. Data Integrity: Trezor Bridge verifies the integrity of data transmitted between the web browser and the Trezor hardware wallet to ensure that it has not been altered or tampered with during transmission. This helps protect against data manipulation attacks that could potentially compromise the security of the device or the user's cryptocurrency assets.

4. API Proxy: Trezor Bridge acts as an API proxy, relaying commands and responses between the web browser and the Trezor hardware wallet. It validates and sanitizes incoming commands to prevent unauthorized or malicious actions that could compromise the security of the device or the user's funds. Similarly, it verifies the authenticity and integrity of responses from the Trezor device before relaying them to the web browser.

5. Firmware Updates: Trezor Bridge provides a secure mechanism for updating the firmware of Trezor hardware wallets. Firmware updates are downloaded from the official Trezor website over a secure connection and verified for authenticity and integrity before being installed on the device. This helps ensure that users receive genuine firmware updates that have not been tampered with or modified by malicious actors.

Overall, Trezor Bridge employs a combination of encryption, authentication, data integrity checks, API proxying, and secure firmware update mechanisms to ensure safe communication between Trezor hardware wallets and computers, protecting the privacy and security of users' cryptocurrency assets against a wide range of potential threats and attacks.
