Secret operations using reconfigurable logics

摘要

An integrated circuit includes a programmable logic device and optionally a control circuit coupled to the programmable logic device (PLD). The control circuit may detect that a reconfiguration criterion is satisfied. Responsive to the reconfiguration criterion being satisfied, the control logic may configure, using one or more randomizations, the PLD to implement a secret operation, wherein a first randomized configuration of the PLD results in a first circuit implementation that is different from, but functionally equivalent to, a second circuit implementation that results from a second randomized configuration of the PLD.

1. An integrated circuit comprising:
a programmable logic device (PLD) having a plurality of gates or logics; and a control circuit coupled to the PLD, wherein the control circuit is to:
detect that a reconfiguration criterion is satisfied; andresponsive to the reconfiguration criterion being satisfied, configure, using one or more randomizations, the PLD to implement a secret operation, wherein a first randomized configuration of the PLD uses a first subset of the plurality of gates or logics and results in a first circuit implementation that is different from, but functionally equivalent to, a second circuit implementation that uses a second subset of the plurality of gates or logics and results from a second randomized configuration of the PLD.
