With symmetric encryption, the same key is used for both encryption and decryption. This ensures that only authorized individuals with the correct key can access the data stored on the device.

2. Public Key Cryptography: Trezor also employs public key cryptography for secure communication and key management. Public key cryptography utilizes a pair of keys: a public key for encryption and a private key for decryption. The receiver’s public key is used to encrypt data, while the private key is kept securely stored on the Trezor device for decryption.

3. Hierarchical Deterministic (HD) Wallets: Trezor uses HD wallets, which provide an additional layer of security. HD wallets derive multiple cryptographic key pairs from a single, randomly generated seed. This means that users only need to remember one seed phrase to access a virtually unlimited number of private keys. HD wallets also make it easier to create secure backups of the wallet.

4. Shamir’s Secret Sharing: Trezor incorporates Shamir’s Secret Sharing algorithm to prevent single points of failure. Shamir’s Secret Sharing divides a secret into multiple parts, or “shares,” which are distributed among different parties. A specified number of shares is required to reconstruct the secret. This ensures that even if one share is compromised, the secret remains secure.

5. Password-Based Encryption: In addition to the above techniques, Trezor allows users to set up a password for an extra layer of protection. This password is used to encrypt the device’s storage, adding an additional level of security to the encrypted data.

Through a combination of symmetric encryption, public key cryptography, HD wallets, Shamir’s Secret Sharing, and password-based encryption, Trezor ensures the security of users’ cryptocurrencies and sensitive data. Understanding these encryption techniques can help users make informed decisions when it comes to securing their digital assets.
