WebAlthough the Ajtai-Dwork cryptosystem has a security proof, Nguyen and Stern [9] gave a heuristic attack to show that the implementations of the Ajtai-Dwork cryptosystem would require very large keys in order to be secure, making it imprac-tical in a real-life environment because of its key size and expansion rate. WebJul 6, 2007 · In particular, we review quantum key distribution via the BB84 protocol and its security proof, as well as the related quantum bit commitment protocol and its proof of insecurity.
