Abstract: Examples associated with printer authentication are described. One example print container includes a space for a supply of print material and an interface for delivering the print material to a printer to which the print container is connected. An authentication module provides an authentication signal to a decrypted module embedded in firmware of the printer. The decrypted firmware module is kept in an encrypted state until decrypted by a decryption module embedded in the firmware of the printer. The decrypted module is decrypted after the decryption module receives a decryption key after release of the printer.

Abstract: The present subject matter relates to an integrated circuit. The integrated circuit includes a first metal layer and a second metal layer capacitively coupled to the first metal layer through a dielectric layer. Further, the second metal layer includes an electron leakage path to provide for leakage of charge from the second metal layer in a predetermined leak time period.

Abstract: One example discloses a peripheral supply component. The peripheral supply component includes a supply item to provide resources on an installed peripheral component, wherein the supply item is a consumable, upgradable, or replacement component on the installed peripheral component. An encoded component is installed with the supply item, wherein the encoded component is employed to generate a message event related to the peripheral component.

Abstract: Examples associated with firmware encryption are described. One example device firmware includes a base module. The base module controls a base function of the device. The device firmware also includes a first encrypted module that modifies a first function of the device. The first encrypted module is inactive until decrypted. A decryption module decrypts the first module using a first encryption key and controls activation of the first encrypted module.
