摘要:
 随着移动互联网以及移动智能终端的普及，移动支付成为越来越频繁的支付方式。针对量子计算给传统的公钥加密系统带来的威胁，利用NTRU算法的抗量子计算以及高效性加解密的特点，同时为了避免NTRU在签名算法上的失效，结合ECC具有高效的签名算法的优势，采用哈希链进行身份认证，设计出一种ECC-NTRU的移动支付加密方案。通过理论分析对比，表明该方案增强了移动支付加密的安全性，可以抗击量子攻击以及中间人攻击，同时对比性能可知该方案可以提高加解密速率，优化系统流畅度。虽然ECC-NTRU相对ECC模型增加了115 KB左右的系统开销，但是相对现在智能手机GB级别的内存，增大的开销完全可以承受，运行速度相比ECC快了几百倍，这极大地提高了智能终端程序的流畅度，因而具有很强的实用性。
Abstract:
 With the popularity of wireless Internet and smart phones,mobile payment has become more and more frequent. For the threat of quantum computation to the traditional public-key encryption system,using the features of anti-quantum computing and high efficien-cy for encryption and decryption of NTRC algorithm and avoiding the failure of NTRU in signature,combined with ECC with the advan-tages of efficient signature algorithm,adopting Hash chain to identity authentication,a mobile payment encryption scheme of ECC-NTRU is designed. By comparison with theoretical analysis,it shows that the scheme is to enhance the security of the encryption mobile payment and fight the attack of quantum and middle. At the same time comparative performance shows this scheme can improve the encryption speed and fluency. Although the ECC-NTRU increases system overhead by about 115 KB compared with ECC,the increasing cost can afford in comparison with smart phones with level of GB of memory,running faster than ECC hundreds,which greatly improves the flu-ency of intelligent terminal program with very strong practicability.
