Research On Data Security Of E-commerce Based On Mixed Encryption

E-commerce is closely linked with Internet technology.The continuous breakthrough of Internet technology has created the basic conditions for the popularization of e-commerce.However,the threat of security in the increasingly hot e-commerce industry has sounded the alarm.With the development of computer technology,traditional encryption algorithms relied on by ecommerce have been insufficient to withstand the superior cracking attacks of existing computers,which is extremely unfavorable for the development of e-commerce in the future.Faced with the increasingly urgent situation,facing the higher security requirements of e-commerce,whether it is the blockchain technology of virtual currency or the optimization of the original algorithm,the idea of hybrid encryption system is proposed for e-commerce.Safe and consider.This article is a study of encryption algorithms for data encryption in the core issues of e-commerce.Currently,data encryption in e-commerce systems is mainly implemented by symmetric encryption algorithms and public key encryption algorithms,and RSA algorithms are most widely used.In comparison,the public key encryption has better security performance but the encryption efficiency is not high,but symmetric encryption is the opposite.The 768-bit RSA algorithm has been powerfully cracked,indicating that the security of the public key encryption algorithm has been somewhat inadequate.In this case,based on the consideration of the requirements of ecommerce,the paper compares several encryption technologies currently used,and adopts the idea of hybrid encryption,and proposes an algorithm model based on two-dimensional codes and an algorithm based on digital signatures.Model,the main research content is:1.From the definition of e-commerce as an entry point,elaborating the status quo of the development of e-commerce and eliciting security problems that hinder the development of ecommerce at present and in the future,especially e-commerce information security.2.The security threats to e-commerce lead to e-commerce security system,in-depth analysis of various levels,especially for the information encryption part of the important research.3.A comparison of the research and development of information security technologies(mainly encryption technologies)in e-commerce,and a detailed introduction to the encryption ideology and features of mainstream encryption algorithms based on symmetric encryption and public key encryption,and proposes an improvement ECDSA signature scheme.4.The design idea of the hybrid encryption scheme is elaborated,and the L-ECC encryption algorithm model based on two-dimension code and the improved digital signature scheme model L-ECDSA based on chaos and elliptic curve are proposed.Performance analysis.5.Using JSP technology to design a common e-commerce system,online ordering system,a brief introduction to its related development technology,and the L-ECDSA model to test the system's signature performance,test results show that this model It has great advantages in terms of security,anti-counterfeiting and processing speed.
