Abstract
Securing an integrated circuit, including fabricating the integrated circuit to include a multiplicity of unblown efuses, at least one surrogate efuse that emulates a blown efuse, non-volatile data representing the blown state of the surrogate efuse, and security circuitry; and setting, by the security circuitry when power is first applied to the integrated circuit, a security state of the integrated circuit in dependence upon whether a sensed state of the surrogate efuse is equal to the blown state of the surrogate efuse.
