摘要
人们在利用各种各样的电子设备进行“面对面”信息交流的过程中,双方都不希望自己的信息被第三方获取,由此衍生了通信安全问题。数据安全性不够,数据传输过程就容易受到外界干扰,造成信息重复、缺失、丢包或延迟等现象的产生。针对此问题,广大科研工作者积极应对,引入了密码系统,采用密码算法对数据进行加密,减少其在传输过程中受到的干扰,进而起到保护数据的效果。为了进一步了解密码算法在网络数据传输中的工作原理,文中选取了非对称密码系统中的RSA算法作为研究对象,详细介绍了该算法的加密解密过程,对比分析了RSA算法和ECC算法的优缺点,并针对RSA算法的缺陷,总结了相应的优化措施和优化效果。最后,总结了RSA算法在网络数据传输中的研究进展和实际运用,并对RSA算法的未来进行了展望,期望为数据保护工作提供一些参考依据。
In the process of people’s“face-to-face”information exchange using various electronic devices,both sides do not want their information to be obtained by the third party,which leads to the problem of communication security.Data security is not enough,the data transmission process is vulnerable to external interference,resulting in information duplication,missing,packet loss or delay.These problems are still not completely avoided.One of the important reasons is that the security of data is not enough,and it is disturbed by the outside world in the transmission process.In response to this problem,the majority of scientific researchers have actively responded,invented data encryption technology and introduced cryptography,which uses cryptographic algorithms to encrypt the data to reduce the interference in the transmission process,thereby protecting the data.In essence,among many technologies that guarantee various functional characteristics of information security,data encryption technology is the core and key technology of information security.Data encryption technology encrypts data from plaintext to ciphertext and communicates through encryption algorithm,and then decrypts the plaintext through corresponding decryption algorithm,which can improve the security of data transmission and ensure the integrity of data transmission.In order to further understand the working principle of cryptographic algorithm in network data transmission,this paper selects the RSA algorithm in asymmetric cryptographic system as the research object,introduces the encryption and decryption process of this algorithm in detail,compares and analyzes the advantages and disadvantages of RSA algorithm and ECC algorithm,and summarizes the corresponding optimization measures and optimization results in view of the defects of RSA algorithm.Finally,the research progress and practical application of RSA algorithm in network data transmission are summarized,and the future of RSA algorithm is prospected,hoping to provide some reference for dat
