A method of mitigating logic upsets includes providing an input to each of a plurality of programmable logic components, processing the input in each programmable logic component, determining an output from each programmable logic component, providing the output from each programmable logic component to a fixed logic component, examining the outputs, and determining a validated output from among the outputs. An architecture for mitigating logic upsets includes an input, a plurality of programmable logic components, and a fixed logic component. The input is provided to each of the programmable logic components. Each programmable logic components includes an encryption algorithm and a first majority voting logic, and processes the respective input to determine a respective output. The fixed logic component includes a second majority voting logic. The fixed logic component receives each respective output from the programmable logic components, examines the outputs, and determines a validated output.
