摘要
提出了一种面向共享用电的RSA改进算法及其应用方案,用以提高用户在共享用电过程中的安全。改进后的RSA加密算法通过对比素数α、β的大小,产生托管密钥分散因子、增加解密的平方根运算等措施,解决了传统RSA算法中密钥长度被分解后,威胁到整体加解密方案的问题。该算法内嵌于密码机和动态二维码模块的安全加解密芯片内,形成安全加解密通信信道,用于保障信息传递及二维码生成过程中内容不被篡改。仿真测试结果表明,该算法的应用使安全攻击行为成功率下降18.28%,降低了用户在下载用电APP、即时扫码和结算信息传递过程中的安全风险,能够有效支撑共享用电的推广应用。
An improved RSA algorithm and its application scheme are proposed to improve the security of users in the process of sharing electricity.By comparing the size of prime numberαandβ,the improved RSA encryption algorithm generates the escrow key dispersion factor,and increases the square root operation of decryption.It solves the problem that the key length in the traditional RSA algorithm is decomposed and threatens the overall encryption and decryption scheme.The algorithm is embedded in the security encryption and decryption chip of the cipher machine and dynamic QR code module,forming a secure encryption and decryption communication channel,which is used to ensure that the content is not tampered with in the process of information transmission and QR code generation.The simulation test results show that the application of the algorithm can reduce the success rate of security attack behavior by 18.28%,reduce the security risk of users in the process of downloading power consumption APP,real-time code scanning and settlement information transmission,and can effectively support the promotion and application of shared power consumption.
