SUPPLY AUTHENTICATION VIA TIMING CHALLENGE RESPONSE |
摘要 |
In an example implementation, an authentication system includes a printer having a controller and a memory. The authentication system also includes an authentication algorithm stored in the memory and executable on the controller to issue a cryptographic timing challenge, and to authenticate a print supply cartridge when the cartridge provides a challenge response corresponding to an expected response within an expected time window. |
