A method for managing communications involving a lockstep processing system comprising at least a first processor and a second processor, the method comprising: receiving, at a data synchronizer, a first signal (S 1) from a first device; receiving, at the data synchronizer, a second signal (S 2) from a second device; determining, by the data synchronizer, whether the first signal (S 1) is equal to the second signal (S 2); and when the first signal (S 1) is not equal to the second signal (S 2), transmitting, by the data synchronizer, a first response signal to the first device and a second response signal to the second device, wherein neither the first signal (S 1) nor the second signal (S 2) are transmitted to the lockstep processing system, wherein the first response signal is unique to the first signal (S 1), and wherein the second response signal is unique to the second signal (S 2); or when the first signal (S 1) is equal to the second signal (S 2): transmitting, by the data synchronizer, the first signal (S 1) to the first processor and the second signal (S 2) to the second processor, wherein transmitting the first signal (S 1) to the first processor occurs synchronously with transmitting the second signal (S 2) to the second processor; receiving, at the data synchronizer, a third signal (S 3), generated in response to receiving the first signal (S 1), from the first processor of the lockstep processing system; receiving, at the data synchronizer, a fourth signal (S 4), generated in response to receiving the second signal (S 2), from the second processor of the lockstep processing system; determining, at the data synchronizer, whether the third signal (S 3) is equal to the fourth signal (S 4); and when the third and fourth signals (S 3 and S 4) are equal to one another, transmitting, by the data synchronizer, the third signal (S 3) to the first device and the fourth signal (S 4) to the second device, wherein transmitting the third signal (S 3) to the first device occurs synchronously with transmitting the fourth signal (S 4) to the second device. receiving, at a data synchronizer, a first signal (S 1) from a first device;
