    摘要: A logic circuit for calculating an encrypted dual-rail result operand from encrypted dual-rail input operands according to a combination rule includes inputs for receiving the input operands and an output for outputting the encrypted result operand. Each operand may comprise a first logic state or a second logic state. The logic circuit comprises a first logic stage connected between the inputs and an intermediate node and a second logic stage connected between the intermediate node and the output. The logic stages are formed to calculate the first or second logic state of the encrypted result operand from the input operands according to the combination rule and to maintain or change exactly once the logic state of the encrypted result operand, independently of an order of arrival of the encrypted input operands, depending on the combination rule, in order to impress the calculated first logic state or second logic state on the output.

    摘要: Circuit for calculating a logic combination of two encrypted input operands recieves first and second dual-rail signals comprising data values in a calculation cycle and precharge values in a precharge cycle, and receives a dual-rail encryption signal comprising encryption values in the calculation cycle and precharge values in the precharge cycle, and outputs a dual-rail result signal comprising encrypted result values in the calculation cycle and precharge values in the precharge cycle. The data and encrypted result values are encrypted with the encryption values of the dual-rail encryption signal according to an encryption rule. A logic circuit determines the encrypted result values according to the logic combination from the data and encryption values, and outputs the encrypted result values in the calculation cycle. A precharge circuit impresses precharge values when precharge values are sensed at a single input, or stops impressing the precharge values only when the first and second dual-rail signals comprise data values and the dual-rail encryption signal comprises encryption values.
