Crypto Terminal: A New Open Device For Securing Blockchain Wallets

This poster introduces the Crypto Terminal, a new open device for securing blockchain wallets. This device includes a processor, a touch screen, a removable smartcard, and a Bluetooth Low Energy (BLE) module. Smartcard is the core security, it manages cryptographic procedures and keys. The terminal is bare metal, i.e. its firmware and the BLE firmware can be erased and uploaded at anytime. The software integrity of the programmer that performs these operations is checked by an innovative integrity probe. A use case is illustrated with a smartphone.
