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. WebFeb 10, 2005 · Abstract. Ajtai and Dwork proposed a public-key encryption scheme in 1996 which they proved secure under the assumption that the unique shortest vector problem is hard in the worst case.
WebIn this article, we give a digital signature by using Lindner–Peikert cryptosystem. The security of this digital signature is based on the assumptions about hardness of Ring-LWE and Ring-SIS problems, along with providing public key and signature of Web宁 卓,石 伟,孙知信(南京邮电大学 物联网学院，江苏 南京 210003)基于格的第三方移动支付加密模型ecc-ntru宁 卓,石 伟,
