Trezor® Hardware® Wallet | (Official)
Trezor hardware wallets: your key to securing digital currencies. Trust in industry-leading security for peace of mind in the crypto world.
The Trezor Wallet handles firmware updates in a secure and transparent manner, employing several security measures to ensure the authenticity and integrity of updates. Here's how the process typically works:
Notification of updates: When a new firmware update is available for the Trezor Wallet, users are notified through the Trezor web interface or the Trezor Suite software (formerly known as Trezor Bridge). Users may receive an alert prompting them to update their device to the latest firmware version.
Verification of update authenticity: Before installing a firmware update, the Trezor Wallet verifies the authenticity of the update to ensure that it has not been tampered with or modified by unauthorized parties. The device checks the digital signature of the firmware update against a trusted public key stored on the device to confirm its authenticity.
Secure download and installation: Once the authenticity of the firmware update has been verified, the Trezor Wallet proceeds to download and install the update securely. The update process typically involves connecting the device to a computer and initiating the update through the Trezor web interface or Trezor Suite software.
Secure boot process: During the firmware update process, the Trezor Wallet employs a secure boot process to ensure that only authenticated and unaltered firmware can be loaded onto the device. This prevents attackers from installing malicious firmware or tampering with the device's operating system to gain unauthorized access.
Physical anti-tamper protections: The Trezor Wallet is designed with physical anti-tamper protections to detect and respond to unauthorized attempts to modify or tamper with the device. These protections may include tamper-evident seals, secure enclosure designs, and sensors that detect physical tampering and trigger security measures.
Open-source firmware: Trezor Wallet firmware is open-source, meaning that the code is publicly available and can be reviewed and audited by security experts and the broader community. This transparency allows users to verify the security and integrity of the firmware and gain confidence in its authenticity.
By implementing these security measures, the Trezor Wallet ensures that firmware updates are downloaded, verified, and installed securely, protecting users' cryptocurrency holdings from unauthorized access and potential threats. Additionally, the open-source nature of the firmware allows for community scrutiny and contributes to the overall security and transparency of the Trezor Wallet ecosystem.
