SUPPLY AUTHENTICATION VIA TIMING CHALLENGE RESPONSE

In an example implementation, a device to facilitate authentication of a print cartridge (104) has a memory (116) and logic (132) to receive a timing challenge from a host device (102) and enable authentication of the cartridge by providing a challenge response in a challenge response time that fall...

Zusammenfassung:	In an example implementation, a device to facilitate authentication of a print cartridge (104) has a memory (116) and logic (132) to receive a timing challenge from a host device (102) and enable authentication of the cartridge by providing a challenge response in a challenge response time that falls within an expected time window, the logic to perform a mathematical calculation in response to the timing challenge, wherein the calculation yields the challenge response within the expected time window.
