摘　　要：随着信息技术的高速发展,电子商务成为未来商务活动的必然趋势。针对目前人们越来越重视电子商务的安全性问题,本文提出了一种应用于电子商务信息加密的L-C映射加密算法。该算法结合了Logistic映射算法和Cubic映射算法,形成新的Logistic-Cubic映射加密算法,简称L-C映射加密算法,并且采用分层迭代模式,再根据加密函数加密得到的密文,得到下一次算法的迭代次数,保证算法的随机性和规律性。算法仿真结果表明,本文提出的这种应用于电子商务信息加密的L-C映射加密算法在本文信息加密和图像信息加密上效果良好,且加密速度比一般的加密算法快,值得推广。With the rapid development of modem information technology, e-commerce becomes the inevitable trend of the future business activities. In view of the security problem which gained more and more attention by people, the paper puts forward a L- C mapping encryption algorithm applied in electronic business information encryption. The algorithm combines the Logistic mapping algorithm and Cubic mapping algorithm, and form a new Logistic- Cubic mapping encryption algorithm, L- C mapping encryption algorithm for short, and using layered iteration model, and then according to the cryptograph encrypted by encryption function, get the next iteration of algorithm, ensuring the randomness and regularity of the algorithm. Algorithm simulation results show that the proposed L - C mapping encryption algorithm applied in electronic business information encryption has a good effect on text information encryption and image information encryption, and the encryption speed is quicker than general encryption algorithm, which is worthy to be popularized.
