Abstract
Systems and methods for protecting intellectual property of a circuit via obfuscation of logic through encryption. The methods comprise: analyzing a combinational circuit (CC) to identify first logic gates that perform first function(s) which is(are) implementable by LUT(s); dividing CC a first portion comprising the first logic gates and a second portion comprising remaining logic gates; protecting gate logic of the first portion by at least storing information implementing the first function(s) in an encrypted LUT format in a memory device of the circuit such that the first function(s) is(are) obfuscated when the circuit is in an at-rest state; and interfacing the remaining logic gates with the memory device such that the circuit is configured to generate an output in accordance with operations of the combinational circuit using the information stored in the encrypted LUT format.
