  • Patent number: 7876893
    Abstract: 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.
