Abstract:
A method for electronically fused encryption key security includes inserting a plurality of inverters between a bank of security fuses and a fuse sense logic module. The method also includes sensing an activated set of the bank of security fuses and the plurality of inverters. The method further includes comparing the sensed activated set of the bank of security fuses and the plurality of inverters with a software key to determine whether at least a substantial match is made.
