This disclosure relates generally to a system and method for authenticating an electronic device may comprise a server configured to transmit an encrypted object, the encrypted object having an image file format, to the electronic device, the encrypted object being encrypted based on a certificate, the electronic device operatively coupled to the server and comprising a processor registered with the server to create a secured communication link between the processor and the server, wherein the certificate corresponds to the processor, the processor having a cryptographic engine configured to decrypt the encrypted object to result in a decrypted graphic, and a user interface operatively coupled to the processor. The user interface may be configured to display the decrypted graphic and receive a user input responsive to the decrypted graphic. The server may authenticate the electronic device based, at least in part, on the user input.
