Detailed Description
Referring to fig. 1, a traceable encrypted data transmission method and system includes the following steps:
the first step is as follows: converting the character string into a byte stream plaintext, designating different codes through Encoding, and converting the character string into codes corresponding to different code pages, wherein the codes are expressed in a byte [ ] form;
the second step is that: encrypting the byte stream plaintext through a public key, wherein the encrypting comprises primary encryption, secondary encryption and tertiary encryption;
the third step: after encryption is completed, a ciphertext is formed and transmitted through a network to obtain sealing;
the fourth step: decrypting the byte stream plaintext through a public key, wherein the decrypting comprises primary decryption, secondary decryption and tertiary decryption;
the fifth step: and after decryption is finished, obtaining a byte stream plaintext, converting the byte stream plaintext into a character string plaintext, and finishing transmission.
Referring to fig. 2, data transmission is performed through an operation terminal, which may be a desktop computer, a notebook, a tablet, or a mobile phone, and may implement fixed-point operation and mobile operation.
Referring to fig. 2 and 3, the user logs in through the operation terminal to perform authentication, so as to ensure the operation security before plaintext encryption.
Referring to fig. 3, whether the user is qualified or not is judged through identity authentication, the user login comprises fingerprint authentication, seal authentication and iris authentication, the fingerprint authentication and the iris authentication are preferentially selected, and the safety factor is high.
Referring to fig. 2 and 4, after the identity authentication is completed, the plaintext operation is performed, and the plaintext operation includes file browsing, file storage, content addition, file encryption, and file destruction.
