Abstract
An integrated circuit (IC) chip includes an intellectual property (IP) core that executes logical operations to perform a function. The IC chip also includes a core wrapper logically encapsulating the IP core such that inputs and outputs to the IP core are funneled through ports of the core wrapper. The IC chip further includes a locking mechanism for controlling communications with the core wrapper. The locking mechanism includes a set of locking elements that gate access to the ports of the wrapper and a lock interface that controls a state of the set of locking elements based on a presence or absence of an authentication key.
