The invention discloses a method for improving RSA reverse decryption difficulty. A quantum key distribution technology and RSA are combined, a method for improving RSA reverse decryption difficulty by utilizing parameter replacement is designed on the premise that the quantum key distribution technology detects that a channel guarantee public key is not stolen, and the mechanism has three different replacement modes: 1) replacing the public key (n, e) with (n, E); (2) replacing the public key (n, e) with (N, e); and (3) replacing the public key (n, e) with (N, E). According to the method, thequantum key distribution technology and RSA are combined, the RSA technology is used for generating public and private keys, and the quantum key distribution technology is used for sending the publickey and monitoring whether eavesdroppers exist. 本发明公开了一种提高RSA反向解密难度的方法，将量子密钥分发技术和RSA相结合，在量子密钥分发技术检测信道保障公钥在没有被窃取的前提下，设计了一种利用参数替换来提高RSA反向解密难度的方法，此机制有三种不同的替换方式，1)将公钥(n,e)替换为(n,E)；2)将公钥(n,e)替换为(N,e)；3)将公钥(n,e)替换为(N,E)。本发明将量子密钥分发技
