Data transmission method and device and electronic equipment

The invention relates to a data transmission method and device and electronic equipment, a first data transmission path and a second data transmission path which are parallel are arranged in the same network environment, and the method comprises the following steps: receiving a communication ciphertext uploaded by the first data transmission path and a judgment plaintext uploaded by the second data transmission path, judging that the lengths of the plaintext and the communication ciphertext are the same, wherein the plaintext is preset and stored in a database, and each judgment plaintext carries a unique identification code; calling the judgment plaintext carrying the identification code in the database according to the unique identification code of the received judgment plaintext; comparing the judgment plaintext carrying the identification code with the received judgment plaintext carrying the identification code in the database, and outputting a comparison result; judging whether the communication ciphert
