Problems solved by technology

[0002] Most of the traditional encryption methods use reversible encryption methods for data transmission. No matter how complicated the reversible encrypted data is in the transmission method or the encryption method, it is theoretically a reversible encryption method after all. The encryptor can transfer the data Perform a series of algorithm encryption with the secret key. In principle, as long as the secret key used in the encryption process is deciphered, there is a great possibility to decipher the ciphertext data. Therefore, in terms of probability, the possibility of deciphering exists, and it is very likely. high
However, if an irreversible encryption algorithm is used for data encryption transmission, deciphering this cannot decipher the ciphertext data, but the same encryption can not restore the ciphertext data to plaintext data, so it is impossible to use irreversible encryption data for data transmission. taken

Abstract

The invention relates to a data encryption method based on NFC chip security authentication. The method comprises the following steps: 1. The correct user name and password are entered by the user through the mobile terminal to verify the login; 2. After the login of the user is confirmed to be successful, a secret key in character string format is generated through the irreversible encryption of the user name, password and timestamp. To prevent the interactive data between the APP mobile terminal (NFC mobile phone) and the server (cloud server) is maliciously tampered with, cross-use of the 'reversible encryption' and the 'irreversible encryption' algorithms is adopted to ensure that interactive data between the mobile and the server terminals is absolutely safe.
