Abstract
A system and method are disclosed for providing a quantum proof key exchange. The method includes generating at a first computing device a random bit ai, encrypting ai using quantum-proof homomorphic encryption ξ to yield ξA(ai), transmitting ξA(ai) to a second computing device, generating at the second computing device a random bit bi, encrypting bi using the quantum-proof homomorphic encryption ξ to yield ξB(bi), transmitting ξB(bi) to the first computing device and generating a common key between the first computing device and the second computing device based on ξA(ai) and ξB(bi).
