DATA TRANSMISSION METHOD AND ELECTRONIC DEVICE

A data transmission method and an electronic device, relating to the technical field of electronics. The present invention simplifies the complexity of user operation and improves the security of data transmission. The method comprises: after receiving an input of transmitting specific data, a first electronic device sends, to a second electronic device, a request of transmitting the specific data; after receiving the request, the second electronic device sends a generated first random number by means of a weak antenna; and the first electronic device is located within a transmitting distance of the weak antenna and receives the first random number, and the first electronic device also sends a generated second random number by means of the weak antenna. The two electronic devices respectively generate session keys by using the first random number and the second number; the first electronic device encrypts the specific data by using the session key generated by the first electronic device and sends the encrypt
