A thirty year-old encryption algorithm has been shown to be able to withstand any attacks that can be mounted against it, even by quantum computers.
Quantum computing has been described as sounding the death knell for most cryptography. This is because the sheer number of computations that can be performed in a short time mean that just about any encrypted message can be revealed, a so called brute force attack.
But according to researchers at the University of Connecticut the algorithm devised in 1978 by a man called Robert McEliece has stumped even quantum computers. The researchers stress that the algorithm could yet be cracked, but for now, it is the safest line of defence in a qubit enabled world.
